The Atacama Cosmology Telescope: High-resolution component-separated maps across one-third of the sky

Posted by dbos Stanford

Kavli Affiliate: Kent Irwin | First 5 Authors: William R. Coulton, Mathew S. Madhavacheril, Adriaan J. Duivenvoorden, J. Colin Hill, Irene Abril-Cabezas | Summary: Observations of the millimeter sky contain valuable information on a number of signals, including the blackbody cosmic microwave background (CMB), Galactic emissions, and the Compton-$y$ distortion due to the thermal Sunyaev-Zel’dovich […]

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

Posted by dbos MIT

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

Posted by klaurent MIT

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

Posted by klaurent MIT

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 […]
