seat 1A.

student deferment to 1A, would be drafted and sent to the front lines in Vietnam.

of 42 type 1a supernovae discovered by the supernova project, et cetera, et cetera.

So type 1a supernova is useful, because it comes from a very weird type of a star.

So not all type 1a's are the same.

to calibrate type 1a supernovae.

supernova called a type 1A Supernova that is always more or less the same

remnant of a type 1A Supernova explosion it appears that the Stellar explosion

But I would argue that quality is 1A.

Turns out the luminous type 1a supernovae have slower light curves.

Here are several of these type 1a supernovae that have been verified through spectroscopy, and whose redshifts have been measured.

I used to host a national talk show on NPR called 1A, and in one of our early programs, I interviewed a descendant of

A more topical discussion might be around the use of GLP-1a's.

And this is what really allowed the type 1a's to become useful in cosmology, and to ultimately lead to this amazing discovery.

And then he took a new set of type 1a supernovae.

You don't know that it's a type 1a, and you don't know it's the redshift until you take a spectrum.

We have kids with glycogen storage disease Type 1A.

uh URS of uh energy in other words a type 1A Supernova can outshine the

and you get a tremendous thermonuclear explosion that's a type 1A Supernova that that is a class A classical Nova takes place when when the the accreted

And this morning, there was a program on "1A," Joshua Johnson, about whether schools teach about the environment, the destruction of the environment.

about 25 or 30 people on the previous paper for the supernova type 1a dark energy discovery.

The ones that are useful for cosmology are the so-called type 1a's.

So that's what gave us confidence that we could use type 1a's to do cosmology.

they they they can be seen at great great distances what makes a type 1A

It's almost like very similar to a, like a type 1A supernova, it turns out, where you kind of have an object

The 20 minute drive home often includes a stop to watch the 109 New to Boston train hurdle under the bridge on Route 1A.

These are overluminous, compared to the more or less vanilla flavored type 1a supernova.

And in those three weeks, some of those 100,000 galaxies will have produced a type 1a supernova.

So with the Kecks, I could get spectra of these type 1a supernovae that at redshifts of, say, 0.455 in this case.

There was Indian paths, but--like they still use today where 1A was an old Indian path that they just kept widening and widening and widening, but that's been a road ever

the circumference plus one is 2 pi r plus h put all that together we get 1al 2 pi H so H is 1 over 2

So if you don't take that into account, and you're looking at some distant type 1a supernova, and you don't know the true luminosity,

Well, this relationship here was first pointed out by Mark Phillips and then Mario Hamuy in Chile gathered a whole bunch of type 1a supernovae

And here's a Hubble picture of it a few weeks later, and it's marked with an arrow, so it's got to be a type 1a supernova.

And lo and behold, the spectrum to within the noise looks very similar to a low redshift type 1a supernova.

Keck Observatory, and these distant supernovae, is the peak brightness of type 1A supernovae had been calibrated so that could be a standard candle. So if you could find a type 1A supernovae

I'm most excited to meet all of you, learn about your stories, have 1AM conversations.
