Cosmic Evolution of Black Holes and Spheroids. V. The Relation Between Black Hole Mass and Host Galaxy Luminosity for a Sample of 79 Active Galaxies
Daeseong Park, Jong-Hak Woo, Vardha N. Bennert +3
We investigate the cosmic evolution of the black hole (BH) mass -- bulge luminosity relation using a sample of 52 active galaxies at and in the BH mass…
Instability of Magnetized Ionization Fronts Surrounding H II Regions
Jeong-Gyu Kim, Woong-Tae Kim
An ionization front (IF) surrounding an H II region is a sharp interface where a cold neutral gas makes transition to a warm ionized phase by absorbing UV photons from central star…
Discovery of an Ultra-Faint Dwarf Galaxy in the Intracluster Field of the Virgo Center : A fossil of the First Galaxies?
In Sung Jang, Myung Gyoon Lee
Ultra-faint dwarf galaxies (UFDs) are newcomers among galaxies, and are the faintest galaxies in the observed universe. To date, they have only been found around the Milky Way Gala…
A Census of Gas Outflows in Type 2 Active Galactic Nuclei
Hyun-Jin Bae, Jong-Hak Woo
We perform a census of ionized gas outflows using a sample of ~23,000 type 2 active galactic nuclei (AGNs) out to z~0.1. By measuring the velocity offset of narrow emission lines,…
The Tip of the Red Giant Branch Distance to the Perfect Spiral Galaxy M74 Hosting Three Core-Collapse Supernovae
In Sung Jang, Myung Gyoon Lee
M74 (NGC 628) is a famous face-on spiral galaxy, hosting three core-collapse supernovae (SNe):SN Ic 2002ap, SN II-P 2003gd, and SN II-P 2013ej. However its distance is not well kno…
Effects of Spiral Arms on Star Formation in Nuclear Rings of Barred-spiral Galaxies
Woo-Young Seo, Woong-Tae Kim
We use hydrodynamic simulations to study the effect of spiral arms on the star formation rate (SFR) occurring in nuclear rings of barred-spiral galaxies. We find that spiral arms c…
Alignments of the Galaxies in and around the Virgo Cluster with the Local Velocity Shear
Jounghun Lee, Soo-Chang Rey, Suk Kim
An observational evidence is presented for the alignment between the cosmic sheet and the principal axis of the velocity shear field at the position of the Virgo cluster. The galax…
The AGN Population in X-ray Selected Galaxy Groups at
Semyeong Oh, John S. Mulchaey, Jong-Hak Woo +6
We use Chandra data to study the incidence and properties of Active Galactic Nuclei (AGN) in 16 intermediate redshift () X-ray-selected galaxy groups in the Chandra…
Nature of the Wiggle Instability of Galactic Spiral Shocks
Woong-Tae Kim, Yonghwi Kim, Jeong-Gyu Kim
Gas in disk galaxies interacts nonlinearly with an underlying stellar spiral potential to form galactic spiral shocks. While numerical simulations typically show that spiral shocks…
Steadily Increasing Star Formation Rates in Galaxies Observed at 3 <~ z <~ 5 in the CANDELS/GOODS-S Field
Seong-Kook Lee, Henry C. Ferguson, Rachel S. Somerville +3
We investigate the star formation histories (SFHs) of high redshift (3 <~ z <~ 5) star-forming galaxies selected based on their rest-frame ultraviolet (UV) colors in the CANDELS/GO…
Three Dimensional Hydrodynamic Simulations of Multiphase Galactic Disks with Star Formation Feedback: II. Synthetic HI 21 cm Line Observations
Chang-Goo Kim, Eve C. Ostriker, Woong-Tae Kim
We use three-dimensional numerical hydrodynamic simulations of the turbulent, multiphase atomic interstellar medium (ISM) to construct and analyze synthetic HI 21 cm emission and a…
A New Optical Survey of Supernova Remnant Candidates in M31
Jong Hwan Lee, Myung Gyoon Lee
We present a survey of optically emitting supernova remnants (SNRs) in M31 based on H and [SII] images in the Local Group Survey. Using these images, we select objects that have…
