🚨🚨 Paper Day! 🚨🚨 Check out our new paper on the dynamics of the HIP-41378 system, which hosts the coldest known super-puff. Our idea is that the planet is NOT puffy, but rather that the transit depth can be explained via a set of oblique exorings. arxiv.org/abs/2410.00641

C/2023 A3 (Tsuchinshan–ATLAS) and the Moon rising over Brisbane. Took this timelapse on 30th September while it was still in the early morning sky. Now it should be visible just after dusk in to the west, near Venus. #comet #timelapse #Astrophotography

Really delighted to share our new paper out in Nature today, led by grad student Jerry Xuan at ET-Lab ! We resolve the first discovered brown dwarf companion GL229 B as a pair of two BDs in a very tight orbit. (thanks in part to Octofitter!) Paper link & thread below:

My new paper is out today on a catalog of stellar companions with pulsation timing in TESS photometry! arxiv.org/abs/2410.19729 Paper thread below ⬇️

Paper alert 🚨 the Vega dust disk is RIDICULOUSLY smooth! ⭕️ Amazing symmetry in the new JWST (below) + HST images in our work led by the amazing Kate + Schuyler indicates that no giant planets are present in the system ❌ 🪐 but Earths/super-Earths/Neptunes may be present! 🌍

a[s]b turns 100! For our ten squared-th ep, we tour astrophysics extremes: the heaviest and lightest, fastest and slowest, brightest and dimmest. To help us, we meet up with old friends to talk dark matter, exoplanets, and how ridiculously long a Ph.D. takes!

1/n I wrote a piece for The Wire highlighting the risks to Indian Astronomy and the budding Indian space sector due to increasing number of satellite constellations such as Starlink, as JIO & Airtel scurry to bring starlink satellite internet to India m.thewire.in/article/space/…

5/n Astronomers need to be at the table to coordinate global mitigation, and argue for accessiblilty to space and the sky as the heritage for all humanity, and not let the modern space race devlove into a East India Company-esque colonial project to benefit a few corporations

This ep we cover the big boy on cosmology campus: LCDM. What can't this model explain about the universe? Shashank gives a tour through galaxies' dark matter hearts and Cormac shows how 1500 (ish? Unclear on this one) supernovae may hint at a flaw in LCDM. astrosoundbites.com/2025/04/12/epi…

500,000 images from NASA Webb Telescope were released and we need YOUR help in identifying them. Check out NASA Citizen Science’s new project GalaxyZoo. Details below ⬇️

A recent paper led by SXS members Yoonsoo Kim and Elias Most (both at Caltech) is in AAS Nova today! This work explores the formation of strongly magnetized "monster" shocks and a transient "black hole pulsar" state from mergers of a magnetized neutron star and a black hole.

In this episode, the (domestic) American sector of Astro[sound]bites covers the recent proposed budget cuts to NASA, the largest in its history. We cover the downsides these cuts would have for science and the economy, and what you can do to speak out. astrosoundbites.com/2025/05/24/epi…

This week, Lucia, Cormac, and Shashank dive into the depth of the Mediterranean Sea and journey to the icy desert of Antarctica to discover more about neutrinos. Photo: first detection of a neutrino in a bubble chamber (1970). astrosoundbites.com/2025/07/05/epi…

Hi!!! Idk if anyone is on Twitter anymore but if you are, this short story chap I've been working on for the last couple years is open for pre-orders thanks to Abode Press!!! Shoutout to desi diaspora oomfs who are looking for a lighthearted but still contemplative read 💜💖💜
