G., Ellison, Sara L., Lau, Marie Wingyee, Martin, Crystal L., Myers, Adam, Rubin, Kate H. R., Simcoe, Robert A.

“…In contrast to measurements along the line-of-sight, regions transverse to quasars exhibit enhanced H I Lyα absorption and a larger variance than the ambient intergalactic medium, with increasing absorption and variance toward smaller scales. …”

Mg II ABSORPTION AT 2 < z < 6 WITH MAGELLAN/FIRE. II. A LONGITUDINAL STUDY OF HI, METALS, AND IONIZATION IN GALACTIC HALOS by Matejek, Michael Scott, Simcoe, Robert A., Cooksey, Kathy, Seyffert, Eduardo N.

“…We speculate that if weaker Mg II systems represent accreting gas as suggested by recent studies of galaxy-absorber inclinations, then their high metal abundance suggests re-accretion of recently ejected material rather than first-time infall from the metal-poor intergalactic medium, even at early times.…”

LIMFAST. II. Line Intensity Mapping as a Probe of High-redshift Galaxy Formation by Guochao Sun, Lluís Mas-Ribas, Tzu-Ching Chang, Steven R. Furlanetto, Richard H. Mebane, Michael O. Gonzalez, Jasmine Parsons, A. C. Trapp

“…The epoch of reionization (EoR) offers a unique window into the dawn of galaxy formation, through which high-redshift galaxies can be studied by observations of both themselves and their impact on the intergalactic medium. Line intensity mapping (LIM) promises to explore cosmic reionization and its driving sources by measuring intensity fluctuations of emission lines tracing the cosmic gas in varying phases. …”

The decay of MHD turbulence and the primordial origin of magnetic fields in cosmic voids by Hosking, DN

“…This has become a popular problem in recent years due to the possibility that the weak magnetic field hosted by the intergalactic medium (IGM) in voids could be a relic from the early Universe [see Durrer & Neronov (2013); Subramanian (2016); Vachaspati (2021) and references therein]. …”

The ATLAS 3D project - VII. A new look at the morphology of nearby galaxies: The kinematic morphology-density relation by Cappellari, M, Emsellem, E, Krajnović, D, McDermid, R, Serra, P, Alatalo, K, Blitz, L, Bois, M, Bournaud, F, Bureau, M, Davies, R, Davis, T, de Zeeuw, P, Khochfar, S, Kuntschner, H, Lablanche, P, Morganti, R, Naab, T, Oosterloo, T, Sarzi, M, Scott, N, Weijmans, A, Young, L

“…This suggests that a different mechanism is at work there, possibly related to the stripping of the gas from spirals by the hot intergalactic medium in the cluster core and the corresponding lack of cold accretion. © 2011 The Authors Monthly Notices of the Royal Astronomical Society © 2011 RAS.…”

A Comprehensive Investigation of Metals in the Circumgalactic Medium of Nearby Dwarf Galaxies by Yong Zheng, Yakov Faerman, Benjamin D. Oppenheimer, Mary E. Putman, Kristen B. W. McQuinn, Evan N. Kirby, Joseph N. Burchett, O. Grace Telford, Jessica K. Werk, Doyeon A. Kim

“…Assuming a metallicity of 0.3  Z _⊙ , we estimate that the dwarf galaxy’s cool CGM likely harbors ∼10% of the metals ever produced, with the rest either in more ionized states in the CGM or transported to the intergalactic medium. We further examine the EAGLE simulation and show that H i and low ions may arise from a dense cool medium, while C iv arises from a diffuse warmer medium. …”

Cross Correlation between the Thermal Sunyaev–Zeldovich Effect and the Integrated Sachs–Wolfe Effect by Ayodeji Ibitoye, Wei-Ming Dai, Yin-Zhe Ma, Patricio Vielva, Denis Tramonte, Amare Abebe, Aroonkumar Beesham, Xuelei Chen

“…We find that this constraint leads to an estimate on the electron temperature today as ${T}_{{\rm{e}}}=({2.40}_{-0.300}^{+0.250})\times {10}^{6}\,{\rm{K}}$ , consistent with the expected temperature of the warm–hot intergalactic medium. Our studies show that the ISW–tSZ cross correlation is capable of probing the properties of the large-scale diffuse gas.…”

García, Javier A. García, Brian Grefenstette, Kristin Madsen, Kaya Mori, Daniel Stern

“…In such galaxies, HEX-P will: 1) provide unique information about X-ray binary populations, including accretor demographics (black hole and neutron stars), distributions of accretion states and state transition cadences; 2) place order-of-magnitude more stringent constraints on inverse Compton emission associated with particle acceleration in starburst environments; and 3) put into clear context the contributions from X-ray emitting populations to both ionizing the surrounding interstellar medium in low-metallicity galaxies and heating the intergalactic medium in the z &gt; 8 Universe.…”
