Survival or Destruction: Effects of Spheroidal Satellite Collisions on Bars in Milky Way-Like Galaxies

Yufan Zhou, Zhiyuan Li, Óscar Jiménez-Arranz +1

Although stellar bars are prevalent in local galaxies, unbarred galaxies constitute a significant fraction, particularly at high redshifts. While some galaxies are unbarred by natu…

Constraints on the Hot Circumgalactic Medium around Nearby L* Galaxies from SRG/eROSITA All Sky Survey

Lin He, Zhiyuan Li

The circumgalactic medium (CGM), a multi-phase gas acting as the dynamic interface between the main body of a normal galaxy and the intergalactic medium, is a key ingredient of the…

Probing the Hot Gaseous Halo of the Low-mass Disk Galaxy NGC 7793 with eROSITA and Chandra

Lin He, Zhiyuan Li, Meicun Hou +3

Galaxy formation models predict that local galaxies are surrounded by hot X-ray-emitting halos, which are technically difficult to detect due to their extended and low surface brig…

Robust detection of hot intragroup medium in optically selected, poor galaxy groups by eROSITA

Dawei Li, Taotao Fang, Chong Ge +7

Over the last several decades, extensive research has been conducted on the baryon cycles within cosmic structures, encompassing a broad mass range from dwarf galaxies to galaxy cl…

Uncovering an Excess of X-ray Point Sources in the Halos of Virgo Late-type Galaxies

Zhensong Hu, Meicun Hou, Zhiyuan Li

We present a systematic search for extraplanar X-ray point sources around 19 late-type, highly inclined disk galaxies residing in the Virgo cluster, based on archival Chandra obser…

CHANG-ES. XXX. 10 kpc Radio Lobes in The Sombrero Galaxy

Yang Yang, Jiang-Tao Li, Theresa Wiegert +8

We report the discovery of the 10 kilo-parsec (kpc) scale radio lobes in the Sombrero galaxy (NGC 4594), using data from the Continuum Halos in Nearby Galaxies - an Expanded Very L…

An X-ray Census of Active Galactic Nuclei in the Virgo and Fornax Clusters of Galaxies with SRG/eROSITA

Meicun Hou, Zhensong Hu, Zhiyuan Li

We present a uniform and sensitive X-ray census of active galactic nuclei (AGNs) in the two nearest galaxy clusters, Virgo and Fornax, utilizing the newly released X-ray source cat…

X-Ray Constraints on the Hot Gaseous Corona of Edge-on Late-type Galaxies in Virgo

Meicun Hou, Lin He, Zhensong Hu +6

We present a systematic study of the putative hot gas corona around late-type galaxies (LTGs) residing in the Virgo cluster, based on archival Chandra observations. Our sample cons…

The HASHTAG project: The First Submillimeter Images of the Andromeda Galaxy from the Ground

Matthew W. L. Smith, Stephen A. Eales, Thomas G. Williams +46

Observing nearby galaxies with submillimeter telescopes on the ground has two major challenges. First, the brightness is significantly reduced at long submillimeter wavelengths com…
