Near-Infrared Photometric Variability of Stars Toward the Orion A Molecular Cloud
YY Ori BM Ori
2014/12/26
We present an analysis of J, H, and Ks time series photometry obtained with the southern 2MASS telescope over a 0.84◦×6◦ region centered near the Trapezium region of the Orion Nebula Clust...
The Canada-UK deep submillimeter survey. VII. Optical and near-infrared identifications for the 14 hour field
formation galaxies:high-redshift
2014/12/26
We present the multiwavelength identifications for 23 sources in the Canada-UK Deep Submillimeter Survey (CUDSS) 14h field. The identifications have been selected on the basis of radio and near-infrar...
The optical and near-infrared properties of galaxies. I. Luminosity and stellar mass functions
luminosity function mass function
2014/12/24
We use a large sample of galaxies from the Two Micron All Sky Survey (2MASS) and the Sloan Digital Sky Survey (SDSS) to calculate galaxy luminosity and stellar mass functions in the local universe. We...
AN INVESTIGATION OF THE DUST CONTENT IN THE GALAXY PAIR NGC 1512/1510 FROM NEAR-INFRARED TO MILLIMETER WAVELENGTHS
IRAC MIPS
2014/12/22
We combine new ASTE/AzTEC 1.1 mm maps of the galaxy pair NGC 1512/1510 with archival Spitzer IRAC and MIPS images covering the wavelength range 3.6-160 μm from the SINGS project. The availability of t...
Filling the gap in the extragalactic census: A study at 21 cm and in the near -infrared
Galaxy The universe Optical detection The surface brightness system The Milky Way
2014/12/9
Fundamental to a complete understanding of galaxy properties, formation, and evolution is a thorough knowledge of the local galaxy population. Until we understand the nearest, most easily detectable g...
Adaptive optics assisted near-infrared polarization measurements of sources in the Galactic Center
Galaxy: center - Polarization - dust, extinction - Infrared: stars
2011/10/11
The goals of this work are to provide NIR polarimetry of the stellar sources in the central pc at the resolution of an 8m telescope for the first time, along with new insights into the nature of the k...
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...
The SAURON Project - XIX. Optical and near-infrared scaling relations of nearby elliptical, lenticular and Sa galaxies
galaxies: bulges – galaxies: elliptical and lenticular, cD – galaxies: photometry – galaxies: structure – galaxies: stellar content – galaxies: fundamental parameters
2011/9/27
[Abridged] We present ground-based MDM V-band and Spitzer/IRAC 3.6um-band photometric observations of the 72 representative galaxies of the SAURON Survey. In combination with the SAURON stellar veloci...
