Observations of Mg II Absorption Near z ~ 1 Galaxies Selected From The DEEP2 Redshift Survey
Observations Absorption Galaxies Selected Redshift Survey
2011/10/13
We study the frequency of Mg II absorption in the outer haloes of galaxies at z = 0.6 - 1.4 (with median z = 0.87), using new spectra obtained of ten background quasars with galaxy impact parameters o...
The mass function of black holes at 1rison of models with observations
mass function black holes comparison models observations
2011/10/19
In this paper, we compare the observationally derived black hole mass function (BHMF) of luminous broad-line quasars (BLQSOs) at 1rawn from the Sloan Digital Sky Survey (SDSS) presented in Kel...
Near Infrared Observations of Comet-Like Asteroid (596) Scheila
Infrared Observations Comet-Like Asteroid Scheila
2011/10/12
steroid (596) Scheila was reported to exhibit a cometary appearance and an increase in brightness on UT 2010 December 10.4. We used the IRCS spectrograph on the 8-m Subaru telescope to obtain medium-r...
New Method for Exploring Super-Eddington AGNs by Near-infrared Observations
accretion: accretion disc—black hole physics— galaxies:active
2011/10/8
We propose a new method to explore the candidate super-Eddington active galactic nuclei (AGNs). We examine the properties of infrared (IR) emission from the inner edge of the dusty torus in AGNs, whic...
Dual-Frequency Observations of 140 Compact, Flat-Spectrum Active Galactic Nuclei for Scintillation-Induced Variability
Flat-Spectrum Active Galactic Nuclei Variability
2011/10/8
The 4.9 GHz Micro-Arcsecond Scintillation-Induced Variability (MASIV) Survey detected a drop in Interstellar Scintillation (ISS) for sources at redshifts z > 2, indicating an apparent increase in angu...

Preliminary Results on VLT K-band Imaging Observations of GRB Host Galaxies
evolution high-redshift Gamma-ray Bursts
2009/5/19
We have obtained K-band imaging observations of Gamma-
Ray Burst (GRB) host galaxies with the near-infrared spectro-imager
ISAAC installed on the Very Large Telescope at Paranal (Chile). The
derive...
We present a new Chandra observation of Tycho’s supernova
remnant with the Advanced CCD Imaging Spectrometer. Multicolor Xray
imaging reveals new details of the outer shock and ejecta. At energies

GMRT and VLA Observations at 49 cm and 20 cm of the HII Region near l = 24.8º, b = 0.1º
Interstellar medium—radio recombination lines—HII regions—envelopes
2010/9/16
We report multi-frequency radio continuum and hydrogen radio recombination line observations of HII regions near l = 24.8◦,b = 0.1◦ using the Giant Metrewave Radio Telescope(GMRT) at 1.28 ...
