Yes, in a way. Think of a single dish radio telescope as a one-pixel camera, where measuring the emission intensity at each point in the sky lets you build up a map. Typically, this is done with high resolution on the…
Paraphrasing: "If you don't want to, don't sideload apps, no one is forcing you to" - do people really not see the problem? It's not that technically unsophisticated users will want to sideload apps. They don't know /…
I came to this thread a bit too late, but if you're interested in the actual signal that Stella found, take a look at the spectrum vs time on the NASA release [1] - third plot on the page, with a convenient slider that…
HST is in a 96-minute orbit, up to half of which is blocked by the Earth, depending on where in the sky you point it. Getting time on it is an extremely competitive process - the recent cycle had over a thousand…
This is a comparison of images, not just catalogs of sources in images. If you look at the image in the linked article, you can easily spot one of the stars that has "gone missing". Looking at the brightness of the…
Sure, that's an excellent point. In case you read late replies: we recognize this, and parameterize the burst energy [1] by a beaming scale factor, \Delta\Omega/4\pi. (It still drops off as the inverse square, though,…
Calling it a "really fast camera" elides much of the actual difficulty. We're trying to tag individual wavefronts of light at different telescopes, record them, and then play them back at a central "correlator" with the…
(I haven't watched the video, but I do have professional expertise on this topic.) With interferometry, you're getting an incomplete sampling of the Fourier transform of the sky image, and if you just invert the…
For pulses or bursts of emission, we like compact objects, just from light-travel-time arguments. I would say that the leading models involve very young, highly magnetic neutron stars ("magnetars"), either embedded in…
Would you care to elaborate on what you find objectionable about Face ID? Just like the fingerprint reader, all data is stored on the device secure enclave, and does not leave the phone. And it's been pretty much fast…
Yes, the authors discuss the implications for scalar-tensor theories, and it doesn't look great for many of them. The Nature News and Views article by Clifford Will [1] offers a decent overview. [1]…
I'm too close to this topic for a chatty comment, but I'll just point to this IAU meeting: "Pulsar Astrophysics: The Next 50 years"[1]. It was held this September at Jodrell Bank, which has always had deep involvement…
> I hold out hope the NS-NS rumor is true, that paper is just taking a bit longer to prepare. Mark October 16th on your calendar.
I guess this is cool, but not really that novel a result (and yeah, it's an ATel, not a paper yet, although that's just a matter of time). We've seen similar burst storms from this FRB source before, which is what…
