Rest-Frame Optical Spectroscopy of Ten z 2 Weak Emission-Line Quasars
Ying Chen, Bin Luo, W. N. Brandt +7
We present near-infrared spectroscopy of ten weak emission-line quasars (WLQs) at redshifts of , obtained with the Palomar 200-inch Hale Telescope. WLQs are an exceptional…
Gemini Near Infrared Spectrograph -- Distant Quasar Survey: Rest-Frame Ultraviolet-Optical Spectral Properties of Broad Absorption Line Quasars
Harum Ahmed, Ohad Shemmer, Brandon Matthews +12
We present the rest-frame ultraviolet-optical spectral properties of 65 broad absorption line (BAL) quasars from the Gemini Near Infrared Spectrograph-Distant Quasar Survey (GNIRS-…
The Nature of the Motions of Multiphase Filaments in the Centers of Galaxy Clusters
Shalini Ganguly, Yuan Li, Valeria Olivares +6
The intracluster medium (ICM) in the centers of galaxy clusters is heavily influenced by the ``feedback'' from supermassive black holes (SMBHs). Feedback can drive turbulence in th…
Shedding New Light on Weak Emission-Line Quasars in the C-H Parameter Space
Trung Ha, Cooper Dix, Brandon M. Matthews +20
Weak emission-line quasars (WLQs) are a subset of Type 1 quasars that exhibit extremely weak LyN V 1240 and/or C IV 1549 emission lines. We investigate the relationship b…
Turbulence in Milky Way Star-Forming Regions Traced by Young Stars and Gas
Trung Ha, Yuan Li, Marina Kounkel +3
The interstellar medium (ISM) is turbulent on all scales and in all phases. In this paper, we study turbulence with different tracers in four nearby star-forming regions: Orion, Op…
Measuring Turbulence with Young Stars in the Orion Complex
Trung Ha, Yuan Li, Siyao Xu +2
Stars form in molecular clouds in the interstellar medium (ISM) with a turbulent kinematic state. Newborn stars therefore should retain the turbulent kinematics of their natal clou…
