FEASTS Combined with Interferometry (II): Significantly Changed HI Surface Densities and Even More Inefficient Star Formation in Galaxy Outer Disks

Jing Wang, Xuchen Lin, Lister Staveley-Smith +12

We update the HI surface density measurements for a subset of 17 THINGS galaxies by dealing with the short-spacing problem of the original VLA HI images. It is the same sample that…

Decoding the Single-peaked HI Spectra of Low Redshift Post-starburst Galaxies

Qifeng Huang, Jing Wang, Sara L. Ellison +3

Recent observations with the Five-hundred-meter Aperture Spherical Telescope (FAST) have revealed abundant reservoirs of neutral hydrogen (HI) in low redshift post-starburst galaxi…

FEASTS: The Fate of Gas and Star Formation in Interacting Galaxies

Shun Wang, Jing Wang, Karen Lee-Waddell +3

We use HI data from the FAST Extended Atlas of Selected Targets Survey (FEASTS) to study the interplay between gas and star formation of galaxies in interacting systems. We build c…

FAST-ASKAP Synergy: Quantifying Coexistent Tidal and Ram Pressure Strippings in the NGC 4636 Group

Xuchen Lin, Jing Wang, Virginia Kilborn +27

Combining new HI data from a synergetic survey of ASKAP WALLABY and FAST with the ALFALFA data, we study the effect of ram pressure and tidal interactions in the NGC 4636 group. We…

MeerKAT view of Hickson Compact Groups: II. HI deficiency in the core and surrounding regions

A. Sorgho, L. Verdes-Montenegro, R. Ianjamasimanana +25

Hickson compact groups (HCGs) offer an ideal environment for investigating galaxy transformation as a result of interactions. It has been established that the evolutionary sequence…

ALMA/ACA CO Survey of the IC 1459 and NGC 4636 Groups: Environmental Effects on the Molecular Gas of Group Galaxies

Bumhyun Lee, Jing Wang, Aeree Chung +30

We present new results of a 12CO(J=1-0) imaging survey using the Atacama Compact Array (ACA) for 31 HI detected galaxies in the IC 1459 and NGC 4636 groups. This is the first CO im…

FEASTS: IGM cooling triggered by tidal interactions through the diffuse HI phase around NGC 4631

Jing Wang, Dong Yang, Se-Heon Oh +14

We use the single-dish radio telescope FAST to map the HI in the tidally interacting NGC 4631 group with a resolution of 3.24 (7 kpc), reaching a 5- column density limit of…
