What Comes After ALMA? Next Gen AtLAST Observatory 

I’m so thrilled that people exist like her to make observations of science ❤

Wow. She is clearly a talented science communicator. Great interview!

It's really great to listen to people that speak so passionately and confidently about their work.

brilliant interview with a brilliant prof who describes everything very clear.

What an absolutely fascinating interview and a great person to interview. Her knowledge and ability to communicate it are outstanding. Made more amazing as not a native English speaker. Loved this!

God, she's bloody bright! Anyway, thanks for the video. This channel is of exceptionally high quality.

Great interview, Fraser!! I could listen to this woman talk all day

Incredible interview! I never knew much about submillimeter astronomy, but this was highly informative! I hope Atlast gets funding

Universe Today produces ALMA favorite videos

Impressive and interesting work that hopefully is going to be a reality soon. Great interview 😃

Great interviu!!! She explains so well! anyone understands! Thank you Fraser!

I hope this will get the required funding! Very exciting topic. Thank you Fraser!

After Aricebo, it's always good to see new observatories come online.

this interview was great!! never was into radio astronomy but this work seems so awesome lol

I was expecting those images of proto planetary discs to have taken from space! Breathtakingly beautiful! Thank you 🙏😁

What a charming and intelligent Italian female observational astrophysicist ! She seems quite passionate and driven. I hope her project gets funded and completed. Putting the 50 meter dish at the site with the existing ALMA array will be a great tool to have available.

Awesome interview, amazing work being done

I love her,! So Instructive! Thanks!

Great interview & looking forward to more.

31:48 Fraser: ".. so you are offering to find half of the matter in the universe" Dr Cicone: "Or More." While smiling like the Cheshire Cat.

Really interesting interwiew with a very good scientist. I was only listening at the beginning and when she started to speak I immediatly recognize she was italian like me....we speak english all the same 😂. Congrats Fraser and I hope the Atlas will be fund.

20 micron surface accuracy over a 50m dish will be challenging!

Bless your heart Fraser.

Wow! Dr Cicone really went into great detail without baffling us too much. Amazing interview. Amazing brain dump! Did I hear right that the entire dish surface has to be perfect to within 20 microns at all times, or is that the positioning accuracy of the dish? Pretty incredible for something so big, outside in the desert!

nice interview, enjoyed this very much.

The open areas of those discs are probably where planets have formed. They clean out their orbits of material to build with.

Keep it up Fraser!

Thanks

before this video I was down a RU-vid rabbit hole, finding myself contemplating the doom of humanity due to our seemingly innate ignorance, but after finding this, I feel better, thank you.

I fell into one of those AI generated Space related videos today. 😟 Then, few minutes later, you uploaded a video with you and your guest in flesh and blood.

Great interview!

That's a great lecture

The secondary antenna/mirror looks like it's almost 10 meters. Hope they build that beast.

Technology at 37:50 mentioned regenerative brake technology in Electric Vehicles and power requirements like Megapack and Solar arrays worthy of consideration by Elon Musk engineers. 😮 superb discussions!

Awesome! ty

Great interview

Great interview Thankyou. 👍

Fantastic peek behind the real work of science and the multidisciplinary competency required to see through such a large project. Great guest, I am so happy english is the language of science it makes it so easy to access it without having to learn a language. I also enjoy the accents with which non native speakers express themselves. If I was Elon Musk I wouldn't have wasted 44 billion dollars and lost 22 billion dollars buying Twitter. I would have funded lots of real fundamental science projects such as this.

cuanta bella telescopio!

She talked about making the telescope powered by renewable energy - I wonder if you could use the main dish to collect sunlight, lol (then I realized that since it's not an optical scope it can probably operate during the day, so that's probably out, lol.)

I always wonder how long scientists take to make their project's acronym spell out a viable word, or even a satisfying word.

Out of curiosity, if a friendly billionaire was to come along and say they want to upgrade all the dishes at ALMA to 20M, how much would that cost and what would the sensitivity and resolution increases be?

How are we able to get such well defined images? With the shenanigans that we have to do to detect extrasolar planets, I'd have thought such planetary discs would've just appeared as a bright blob of light.

Talk idea: Interferometer software filters. LIGO uses them and so does the VLA right?

🙌

I actually don't get what a 50m single dish can do what ALMA can't. The conversation did not provide the numbers. Its total aperture is only a third of ALMA's fifty four 12m dishes, so SNR has to be lower. Its resolution is way below ALMA's in interferometer mode. What I heard is that it would have good SNR and resolution *while* having a large field-of-view (more than one square degree), IOW: it can be a survey telescope. Which is good, no question... until you consider what enormous PITA is it to build a 50 meter parabolic reflector to ~30um surface tolerance, and to KEEP that tolerance in a high desert conditions. Compared to this, 12m ALMA dishes are "extremely easy" because they are that much smaller. Notice how DSN is *getting rid* of its 64m antennae because they are too costly to maintain (they switch to arraying several 34m antennae because those are far cheaper, AND they can do two other things at once when do not need to be in array mode!). And _these_ 64m dishes are NOT at submillimeter tolerances, and are NOT in the high mountainous desert where everything costs at least 3x more - and yet, they are too costly. There are many other things that can be done at ALMA. Adding outrigger dishes to increase resolution of the interferometer - incremental work, every new dish just adds a bit more resolution, no new gigantic costly dish designs. Adding separate correlators so that array can be split into several subarrays, this can allow to run survey, or even several separate concurrent surveys (!) with existing dishes. The usual upgrades to receivers, correlator, electronics.

Alma is also a great little city in Quebec, Canada. I know, I grew up there.

Would a solar sail continue accelarating even after crossing the heliosphere?

I did not understand why the telescope has to move very fast

So wot is the nature of these planetary systems at the minute?

Strange, but true. Claudia is a cousin of, an even more famous Cicone... let me see..Ah! 'Madonna'.

Gonna go out on a limb with an educated guess. Manufacturing that precision on that large of an area is going to be difficult and costly. Even with a CAD design - It doesn't mean it will work in real world environment.. Just the temperature differences will be a bitch

What would it cost to build an AU-radius spherical telescope by sprinkling cubesats with cameras/antennas, using solar panels as make-shift solar sails for maneuvering, on a constellation of close-to-polar orbit around the Sun, Startlink/GPS style, using mesh networking so they don't have to be strong enough to reach Earth, just the nearest cubsesat in the constellation, and relay their data till reaching Earth? And what kind of data could we expect to get from something like that? If the cubesats were launched at the same rate as Starlink have been launched on average, how long until we could get the full sphere?

Is the accuracy of the dimension achieved with micro pistons behind the skin of the reflective surface?

thank you . ( 2024 / May / 13 )

Listening at 2x speed was a mistake

Ermm. Where have your past interviews gone?

I can't even listen to ..... ahh I'm only joking, this was good.

If they are new they are only new to us because they are light years away. Which means they are how many ever light years new. Not arguing. Just saying.

Nice real pics thanks. Like to see even if folks do not like them.

Hi, Fraser. Could you please help me understand the details of her design and application. It was a bit challenging to keep up with her because her accent is not familiar to me. Please, sir.

Thank you, I want to see more REAL pictures, not artists rendition.

6 😂

Hey wow! I think I saw God in those images, hard at work creating stuff... Nope! Sorry... That was just my imagination. It was actually Santa Claus...

She's cute

Sexy accent.

Fake.

Once again I can't understand your guests
