My Monday inbox includes email from the Royal Astronomical Society highlighting that Jodrell Banks is at risk of closure. This is both a historic site and a super important research facility. This is one of the few facilities capable of both radio astronomy and radar measurements of space objects.

Alongside my multiple to be read piles, as a fiber hobbyest , I also have the to be wound pile. Anyone else have this kind of pile building up?

It lasted less than 10min

This Science news lede is brilliant. www.sciencenews.org/article/hobb...

Better now

Feels bad, man . Really really bad.

Here is the image directly: use it, share it, print it.

The car can not detect the key. I am pushing the button with the fob. Car starts flashing things and then locks up with a symbol I've never seen on the dash - a car with a key. Car: I said, you can't make me Me: Fine, I'll just bike the 4 miles to the start of the 24 mile ride. What evs. Car: No

I’m giving a talk at the Arch tonight and it just might be clear for the star pastry after!

When the weather would like you dead and decides to bring multiple weapons.

BUT finally saw the babies today.

This is the first time we've seen a remnant of 2 stars that both went supernova. Super cool result.

To demo this is 2 interacting supernovae remnants rather than 2 overlapping remnants, they first verify they are at roughly the same distance and then use models to confirm that what they see can be matched by simulations. YES! There is very low probability this is a chance alignment. Is real pair

There appears to be a shock slamming into a cloud and creating a shock along an filament of material.

The different boundaries are actually associated with different kinds of Gamma Ray production (electron versus proton interactions).

Different wavelengths of Gamma Ray have different energies. Looking in these different energies allows two different remnants with different energies to appear

This is a super bright source of gamma rays too. These high-energy photons come from different kinds of particle collisions that can be associated with light hitting surrounding materials in a shell around supernova.

Trying to understand IC443 Complex, they think they have unravelled the remnants of two massive stars and their corresponding supernovae. This is getting published in Nature Communications... I need to go read this.

Up next: "Unveiling the First Binary-System Supernovae" Miltiadis Michailidis (Kavli Institute for Particle Astrophysics and Cosmology (KIPAC)/Stanford University/SLAC National Accelerator Laboratory) (I'm utterly failing to keep up with this speaker)

Feedback modes Very with Environment AND on what kind of light you're looking at. In LIRGs, clusters are dusty and over-pressured (that has them expanding). Interestingly, PHANGs work looking at early universe sees underpressured if I'm reading this right.... I need to go find their preprint.

But what about extreme environments... like in the early universe. Can't see those systems in detail, but Luminous Infrared Galaxies in the nearby universe are analogous

We understand normal galaxies well.

Her work focuses on how pre-supernovae massive stars (and anything else that's already formed) impact their surroundings and disrupt the cloud of material around them. This is a process driven by UV radiation pressure on the dust, and also IR (re)Radiation exerting pressure as well

Up next: "Dusty and Over-Pressured: Measuring Stellar Feedback in the Closest Luminous Infrared Galaxy" Deb/Debosmita Pathak (The Ohio State University/IPAC) She is looking at how forming stars can effect the formation of even more stars in their surroundings.

While these galaxies are near, what we learn informs us about what was happening in the early universe (when things were structurally more chaotic, but star formation was going strong)

Stages judged by what is in the clusters. More dust = Nurseries Nothing but stars = Mature

Studied 2 ring shaped star forming regions in nearby galaxies using ALMA and VLA radio data. (These are super pretty IMHO. ) While both systems have rings, the galaxies are very different, with an active galactic nuclui in one but not the other. Question? Are they at the same stage?

The issue is, these systems are rich in dust (used to form stars), and the thing that lets them be so cool also hides their optical light. What optical hides, radio light reveals. This allows size and mass to be measured.
