X-ray Halos of Early-Type Galaxies with AGN Feedback and Accretion from a Circumgalactic Medium: models and observations

Silvia Pellegrini, Luca Ciotti, Zhaoming Gan +2

The knowledge of the X-ray properties of the hot gas halos of early-type galaxies has significantly advanced in the past years, for large and homogeneously investigated samples. We…

Luminosity Evolution of the Hot Gas in Normal Galaxies from the Near Universe to z=0.5

Dong-Woo Kim, Giuseppina Fabbiano

We explore the evolution of the ~107 degree hot gas in normal galaxies out to redshift = 0.5 (lookback time = 5 Gyr), using X-ray luminosity functions (XLF) built from a sample of…

Revisiting X-ray-Bright-Optically-Normal-Galaxies with the Chandra Source Catalog

Dong-Woo Kim, Amanda Malnati, Alyssa Cassity +3

X-ray bright optically normal galaxies (XBONGs) are galaxies with X-ray luminosities consistent with those of active galactic nuclei (AGNs) but no evidence of AGN optical emission…

The Chandra Source Catalog Normal Galaxy Sample

Dong-Woo Kim, Alyssa Cassity, Binod Bhatt +4

We present an extensive and well-characterized Chandra X-ray Galaxy Catalog (CGC) of 8557 galaxy candidates in the redshift range z ~ 0.04 - 0.7, optical luminosity 1010 - 1011 Lro…

X-ray scaling relations of early-type galaxies in IllustrisTNG and a new way of identifying backsplash objects

Yunchong Wang, Mark Vogelsberger, Dong-Woo Kim +9

We investigate how feedback and environment shapes the X-ray scaling relations of early-type galaxies (ETGs), especially at the low-mass end. We select central-ETGs from the Illust…

The Hot Interstellar Medium

Emanuele Nardini, Dong-Woo Kim, Silvia Pellegrini

The interstellar medium (ISM) of galaxies very often contains a gas component that reaches the temperature of several million degrees, whose physical and chemical properties can be…
