Estimating black hole masses in young radio sources using CFHT spectroscopy
Minfeng Gu, Soojong Pak, Luis C. Ho
The correlation between black hole masses and stellar velocity dispersions provides an efficient method to determine the masses of black holes in active galaxies. We obtained optic…
Three-Dimensional Observations of H_2 Emission around Sgr A East - I. Structure in the Central 10 Parsecs of Our Galaxy
Sungho Lee, Soojong Pak, Minho Choi +6
We have obtained velocity-resolved spectra of the H_2 v=1-0 S(1) (lambda = 2.1218 micron) emission line at 2 arcsec angular resolution (or 0.08 pc spatial resolution) in four regio…
The WEBT Campaign on the Blazar 3C279 in 2006
M. Boettcher
The quasar 3C279 was the target of an extensive multiwavelength monitoring campaign from January through April 2006, including an optical-IR-radio monitoring campaign by the Whole…
An Optical Source Catalog of the North Ecliptic Pole Region
Narae Hwang, Myung Gyoon Lee, Hyung Mok Lee +13
We present a five (u*,g',r',i',z') band optical photometry catalog of the sources in the North Ecliptic Pole (NEP) region based on deep observations made with MegaCam at CFHT. The…
Variability of the NGC 1333 IRAS 4A Outflow: Molecular Hydrogen and Silicon Monoxide Images
Minho Choi, Klaus W. Hodapp, Masahiko Hayashi +3
The NGC 1333 region was observed in the H2 1-0 S(1) line. The H2 images cover a 5' x 7' region around IRAS 4. Numerous H2 emission features were detected. The northeast-southwest b…
Multi-colour optical monitoring of eight red blazars
Minfeng Gu, C. -U. Lee, Soojong Pak +2
We present the observational results of multi-colour optical monitoring of eight red blazars from 2003 September to 2004 February. The aim of our monitoring is to investigate the s…
