Measuring the Interstellar Medium Content of Nearby, Luminous, Type 1 and Type 2 QSOs through CO and [C ii]
The Astrophysical JournalWe present observations of CO(1–0) and CO(2–1) lines from the Institut de radioastronomie millimétrique 30 m telescope toward 20 nearby, optically luminous type 2 quasars (QSO2s) and observations of the [C ii ] 158 μ m line from the Stratospheric ...Yuanze Luo, A.

, 2009 We present optical and mid-infrared photometry of a statistically complete
sample of 29 very faint dwarf galaxies (M_r > -15 mag) selected from the SDSS
spectroscopic sample and observed in the mid-infrared with Spitzer IRAC. This
sample contains nearby (Abazajian, Adelmen-McCarthy, Allenmandola, Assef, Blanton, Blanton, Boselli, Calzetti, Calzetti, Dale, David W.

, 2018 Major galaxy mergers are thought to play an important part in fuelling the
growth of supermassive black holes. However, observational support for this
hypothesis is mixed, with some studies showing a correlation between merging
galaxies and luminous ...A DasGupta, A Sesana, AD Goulding, AK Weigel, Anna Weigel, B Groves, Benny Trakhtenbrot, C Leitherer, C Ricci, C Ricci, C Villforth, C-L Hung, Chao-Ling Hung, Claudio Ricci, D Kocevski, D Narayanan, D Patton, David B.

The Astrophysical JournalThe first public 0.9–4.4 μ m NIRCam images of the North Ecliptic Pole Time Domain Field uncovered galaxies displaying point-source features in their cores as seen in the longer-wavelength filters. We visually identified a sample of 66 galaxies (∼1 galaxy Rafael Ortiz III, Rogier A. Windhorst, Seth H. Cohen, Steven P. Willner, Rolf A. Jansen, Timothy Carleton, Patrick S. Kamieneski, Michael J.

, 2012 Lenticular galaxies with M_B < -21.5 are almost exclusively unbarred, whereas
both barred and unbarred objects occur at fainter luminosity levels. This
