X-ray metal line emission from the hot circumgalactic medium: probing the effects of supermassive black hole feedback

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Nhut Truong, Annalisa Pillepich, Dylan Nelson, Ákos Bogdán, Gerrit Schellenberger | Summary: We derive predictions from state-of-the-art cosmological galaxy simulations for the spatial distribution of the hot circumgalactic medium (CGM, ${rm [0.1-1]R_{200c}}$) through its emission lines in the X-ray soft band ($[0.3-1.3]$ keV). In particular, we compare […]

EIGER IV: The cool 10$^4$K circumgalactic environment of high-$z$ galaxies reveals remarkably efficient IGM enrichment

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Rongmon Bordoloi, Robert A. Simcoe, Jorryt Matthee, Daichi Kashino, Ruari Mackenzie | Summary: We report new observations of the cool diffuse gas around 29, $2.3<z<6.3$ galaxies, using deep JWST/NIRCam slitless grism spectroscopy around the sightline to the quasar J0100+2802. The galaxies span a stellar mass range […]

Mapping the imprints of stellar and AGN feedback in the circumgalactic medium with X-ray microcalorimeters

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Gerrit Schellenberger, Ákos Bogdán, John A. ZuHone, Benjamin D. Oppenheimer, Nhut Truong | Summary: The Astro2020 Decadal Survey has identified the mapping of the circumgalactic medium (CGM, gaseous plasma around galaxies) as a key objective. We explore the prospects for characterizing the CGM in and around nearby […]

Structure, Kinematics, and Observability of the Large Magellanic Cloud’s Dynamical Friction Wake in Cold vs. Fuzzy Dark Matter

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Hayden R. Foote, Gurtina Besla, Philip Mocz, Nicolás Garavito-Camargo, Lachlan Lancaster | Summary: The Large Magellanic Cloud (LMC) will induce a dynamical friction (DF) wake on infall to the Milky Way (MW). The MW’s stellar halo will respond to the gravity of the LMC and the dark […]

The Clock and the Pizza: Two Stories in Mechanistic Explanation of Neural Networks

Kavli Affiliate: Max Tegmark | First 5 Authors: Ziqian Zhong, Ziming Liu, Max Tegmark, Jacob Andreas, | Summary: Do neural networks, trained on well-understood algorithmic tasks, reliably rediscover known algorithms for solving those tasks? Several recent studies, on tasks ranging from group arithmetic to in-context linear regression, have suggested that the answer is yes. Using […]
