An HI study of a large sample of ultra-diffuse galaxies
Ruilei Zhou, Ming Zhu, Chuan-Peng Zhang +5
By cross-matching the SMUDGes catalog with the FASHI and ALFALFA HI surveys, we construct an HI-detected sample of 112 ultra-diffuse galaxies (UDGs) and 48 low-surface-brightness (…
The nature of Cloud-9: a compact core embedded in a diffuse envelope
Ruilei Zhou, Ming Zhu, Chuan-Peng Zhang +1
We present new HI observations of Cloud-9 with the Five-hundred-meter Aperture Spherical Telescope (FAST), measuringvtotal flux of 0.35 +- 0.03 Jy km/s. Combined with Very Large Ar…
Characterizing Stellar and Gas Properties in NGC 628: Spatial Distributions, Radial Gradients, and Resolved Scaling Relations
Peng Wei, Hu Zou, Jing Wang +8
Building on our previous research of multi-wavelength data from UV to IR, we employ spectroscopic observations of ionized gas, as well as neutral hydrogen gas obtained from the Fiv…
Deep HI Mapping of M 106 Group with FAST
Yao Liu, Ming Zhu, Hai-Yang Yu +6
We used FAST to conduct deep HI imaging of the entire M 106 group region, and have discovered a few new HI filaments and clouds. Three HI clouds/filaments are found in a region con…
