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

Posted by dbos July 3, 2023MIT

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 […]

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

Posted by klaurent July 3, 2023Tokyo

Kavli Affiliate: Toshiya Namikawa | 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 […]

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

Posted by klaurent July 3, 2023February 17, 2026Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho |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 (tSZ) effect. Extracting new insight into cosmological and astrophysical questions often requires combining multi-wavelength observations to spectrally isolate one […]

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

Posted by klaurent June 30, 2023July 18, 2023MIT

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 June 30, 2023MIT

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 […]
