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

Posted by klaurent July 3, 2023MIT

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

Posted by klaurent 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 […]

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

Posted by klaurent July 3, 2023July 18, 2023MIT

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 […]

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 […]

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 […]
