I am Chuan-Peng Zhang, an astronomer working at the National Astronomical Observatories, Chinese Academy of Sciences (NAOC) as an associate professor now, and was ever at the Max-Planck-Institut für Astronomie (MPIA) as a postdoc.

My research interests are extragalactic H I objects, extragalactic OH megamasers, early high-mass star formation including giant molecular clouds, infrared dust bubbles, infrared dark clouds, hyper-compact HII regions, fragmentation and deuteration in high-mass star formation.

Current Work

Smiley face The FAST All Sky H I survey (FASHI) was designed to cover the entire sky observable by the Five-hundred-meter Aperture Spherical radio Telescope (FAST), spanning approximately 22000 square degrees of declination between −14deg and +66deg , and in the frequency range of 1050-1450 MHz, with the expectation of eventually detecting more than 100000 H I sources. Between August 2020 and June 2023, FASHI had covered more than 7600 square degrees, which is approximately 35% of the total sky observable by FAST. It has a median detection sensitivity of around 0.76 mJy/beam and a spectral line velocity resolution of ∼6.4 km/s at a frequency of ∼1.4 GHz. As of now, a total of 41741 extragalactic H I sources have been detected in the frequency range 1305.5-1419.5 MHz, corresponding to a redshift limit of z ~ 0.09. By cross-matching FASHI sources with the Siena Galaxy Atlas (SGA) and the Sloan Digital Sky Survey (SDSS) catalogs, we found that 16972 (40.7%) sources have spectroscopic redshifts and 10975 (26.3%) sources have only photometric redshifts. Most of the remaining 13794 (33.0%) H I sources are located in the direction of the Galactic plane, making their optical counterparts difficult to identify due to high extinction or high contamination of Galactic stellar sources. Based on current survey results, the FASHI survey is an unprecedented blind extragalactic H I survey. It has higher spectral and spatial resolution and broader coverage than the Arecibo Legacy Fast ALFA Survey (ALFALFA). When completed, FASHI will provide the largest extragalactic H I catalog and an objective view of H I content and large-scale structure in the local universe.
