SDSS-IV MaNGA: Properties of galaxies with kinematically decoupled stellar and gaseous components
Yifei Jin, Yanmei Chen, Yong Shi +30
We study the properties of 66 galaxies with kinematically misaligned gas and stars from MaNGA survey. The fraction of kinematically misaligned galaxies varies with galaxy physical…
The Nuclear Activities of Nearby S0 Galaxies
Mengyuan Xiao, Qiusheng Gu, Yanmei Chen +1
We present a study of nuclear activities in nearby S0 galaxies. After cross-matching the Sloan Digital Sky Survey Data Release 7 (SDSS DR7) with the Third Reference Catalog of Brig…
The growth of the central region by acquisition of counter-rotating gas in star-forming galaxies
Yan-Mei Chen, Yong Shi, Christy A. Tremonti +29
Galaxies grow through both internal and external processes. In about 10% of nearby red galaxies with little star formation, gas and stars are counter-rotating, demonstrating the im…
Narrow C IV absorption doublets on quasar spectra of the Baryon Oscillation Spectroscopic Survey
Chen Zhi-fu, Gu Qiu-sheng, Zhou Luwenjia +1
In this paper, we extend our works of Papers I and II, which are assigned to systematically survey \CIVab\ narrow absorption lines (NALs) with \zabs\zem\ on quasar spectra of…
The Data Reduction Pipeline for the SDSS-IV MaNGA IFU Galaxy Survey
David R. Law, Brian Cherinka, Renbin Yan +26
Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) is an optical fiber-bundle integral-field unit (IFU) spectroscopic survey that is one of three core programs in the four…
Diffuse Gas in Retired Galaxies: Nebular Emission Templates and Constraints on the Sources of Ionization
Jonas Johansson, Tyrone E. Woods, Marat Gilfanov +3
We present emission line templates for passively evolving ("retired") galaxies, useful for investigation of the evolution of the ISM in these galaxies, and characterization of thei…
