Host galaxies of high-redshift extremely red and obscured quasars
Nadia L. Zakamska, Ai-Lei Sun, Michael A. Strauss +9
We present Hubble Space Telescope 1.4-1.6 micron images of the hosts of ten extremely red quasars (ERQs) and six type 2 quasar candidates at z=2-3. ERQs, whose bolometric luminosit…
Morphology of AGN Emission Line Regions in SDSS-IV MaNGA Survey
Zhicheng He, Ai-Lei Sun, Nadia L. Zakamska +6
Extended narrow-line regions (NLRs) around active galactic nuclei (AGN) are shaped by the distribution of gas in the host galaxy and by the geometry of the circumnuclear obscuratio…
Imaging Extended Emission-Line Regions of Obscured AGN with the Subaru Hyper Suprime-Cam Survey
Ai-Lei Sun, Jenny E. Greene, Nadia L. Zakamska +9
Narrow-line regions excited by active galactic nuclei (AGN) are important for studying AGN photoionization and feedback. Their strong [O III] lines can be detected with broadband i…
SCARLET: Source separation in multi-band images by Constrained Matrix Factorization
Peter Melchior, Fred Moolekamp, Maximilian Jerdee +4
We present the source separation framework SCARLET for multi-band images, which is based on a generalization of the Non-negative Matrix Factorization to alternative and several sim…
No sign of strong molecular gas outflow in an infrared-bright dust-obscured galaxy with strong ionized-gas outflow
Yoshiki Toba, Shinya Komugi, Tohru Nagao +4
We report the discovery of an infrared (IR)-bright dust-obscured galaxy (DOG) that shows a strong ionized-gas outflow but no significant molecular gas outflow. Based on detail anal…
Ionized gas outflows in infrared-bright dust-obscured galaxies selected with WISE and SDSS
Yoshiki Toba, Hyun-Jin Bae, Tohru Nagao +5
We present the ionized gas properties of infrared (IR)-bright dust-obscured galaxies (DOGs) that show an extreme optical/IR color, , selected with the Sl…
Ground-Based Mid-Infrared Study of the Compton-Thick AGN in M51 at 10-100 pc Scale
Youichi Ohyama, Satoki Matsushita, Nagisa Oi +1
We performed near-diffraction-limited (~0.4 FWHM) N-band imaging of one of the nearest Active Galactic Nucleus (AGN) in M51 with 8.2m Subaru telescope to study the nuclear structur…
Sizes and Kinematics of Extended Narrow-Line Regions in Luminous Obscured AGN Selected by Broadband Images
Ai-Lei Sun, Jenny E. Greene, Nadia L. Zakamska
To study the impact of active galactic nuclei (AGN) feedback on the galactic ISM, we present Magellan long-slit spectroscopy of 12 luminous nearby type 2 AGN (L_bol~10^{45.0-46.5}…
ALMA Observations of a Candidate Molecular Outflow in an Obscured Quasar
Ai-Lei Sun, Jenny E. Greene, Nadia L. Zakamska +1
We present Atacama Large Millimeter/Submillimeter Array (ALMA) CO (1-0) and CO (3-2) observations of SDSS J135646.10+102609.0, an obscured quasar and ultra-luminous infrared galaxy…
Extended X-ray Emission From a Quasar-Driven Superbubble
Jenny E. Greene, David Pooley, Nadia L. Zakamska +2
We present observations of extended, 20-kpc scale soft X-ray gas around a luminous obscured quasar hosted by an ultra-luminous infrared galaxy caught in the midst of a major merger…
The Processing of the Clumpy Molecular Gas in the Galactic Center and the Star-Formation
Hauyu Baobab Liu, Paul T. P. Ho, Melvyn C. H. Wright +5
We present the Green Bank 100m Telescope (GBT) mapping observations of CS 1-0, and the Submillimeter Array (SMA) 157-pointings mosaic of the 0.86 mm dust continuum emission as well…
A method for the microlensed flux variance of QSOs
Jeremy Goodman, Ai-Lei Sun
A fast and practical method is described for calculating the microlensed flux variance of an arbitrary source by uncorrelated stars. The required inputs are the mean convergence an…
Refining the M_BH-V_c scaling relation with HI rotation curves of water megamaser galaxies
Ai-Lei Sun, Jenny E. Greene, C. M. Violette Impellizzeri +3
Black hole - galaxy scaling relations provide information about the coevolution of supermassive black holes and their host galaxies. We compare the black hole mass - circular veloc…
Using Megamaser Disks to Probe Black Hole Accretion
Jenny E. Greene, Anil Seth, Mark den Brok +7
We examine the alignment between H_2O megamaser disks on sub-pc scales with circumnuclear disks and bars on <500 pc scales observed with HST/WFC3. The HST imaging reveals young sta…
ISM Processing in the Inner 20 pc in Galactic center
Hauyu Baobab Liu, Paul T. -P. Ho, Melvyn C. H. Wright +5
We present the Submillimeter Array (SMA) 157-pointing mosaic in 0.86 mm dust continuum emission with 5.2 angular resolution, and the NRAO Green Bank 100m Telescope (GB…
Milky Way Supermassive Black Hole: Dynamical Feeding from the Circumnuclear Environment
Hauyu Baobab Liu, Pei-Ying Hsieh, Paul T. P. Ho +4
The supermassive black hole (SMBH), Sgr A*, at the Galactic Center is surrounded by a molecular circumnuclear disk (CND) lying between 1.5-4 pc radii. The irregular and clumpy stru…
Importance of far-infrared mapping in a spiral galaxy: AKARI observation of M81
