Structure of bright 2MASS galaxies: 2D fits to the K-S-band surface brightness profiles
2MASS K-S-band surface brightness profiles
2014/12/24
The unprecedented sky coverage and photometric uniformity of the Two Micron All Sky Survey (2MASS) provides a rich resource for obtaining a detailed understanding of the galaxies populating our local ...
CO luminosity functions for far-infrared- and B-band-selected galaxies and the first estimate for Omega(H I+H2)
surveys molecules
2014/12/24
We derive a nonparametric CO luminosity function using an FIR- and an optical B-band-selected sample of the galaxies included in the FCRAO Extragalactic CO Survey. The FIR-selected sample is defined u...
Detection of Ks-band Thermal Emission from WASP-3b
planetary systems Ks-band Thermal Emission WASP-3b
2012/2/23
We report the detection of thermal emission from the hot Jupiter WASP-3b in the KS band, using a newly developed guiding scheme for the WIRC instrument at the Palomar Hale 200in telescope. Our new gui...
Extreme Emission Line Galaxies in CANDELS: Broad-Band Selected, Star-Bursting Dwarf Galaxies at z>1
Extreme Emission Galaxies CANDELS: Broad-Band Selected Star-Bursting Dwarf Galaxies
2011/10/17
We identify an abundant population of extreme emission line galaxies (EELGs) at redshift z~1.7 in the Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey (CANDELS) imaging from Hubble Space Teles...
W-band prototype of platelet feed-horn array for CMB polarisation measurements
platelet feed-horn array polarisation measurements
2011/9/28
We present the design and performance of a 2x2 prototype array of corrugated feed-horns in W-band. The module is fabricated using a so-called "platelet" technique by milling Aluminum plates. This tech...

Planetary Using Innovative Background Subtraction Technique
2011/9/28
Multi-wavelength observations/spectroscopy of exoplanetary atmospheres are the basis of the emerging exciting field of comparative exoplanetology. The HR 8799 planetary system is an ideal laboratory t...
X-ray spectroscopy of Abell S1101 with Chandra, XMM-Newton and ROSAT: band-pass dependence of he temperature profile and soft excess emission
X-ray spectroscopy Chandra band-pass dependence temperature profile soft excess emission
2011/9/28
We present spatially-resolved spectroscopy of the galaxy cluster Abell S1101, also known as Sersic 159-03, with Chandra, XMM-Newton and ROSAT, and investigate the presence of soft X-ray excess emissio...
Identification of H$_2$CCC as a diffuse interstellar band carrier
general lines and bands ISM molecules methods laboratory techniques spectroscopic
2010/11/9
We present strong evidence that the broad, di use interstellar bands (DIBs) at 4881 and
5450A are caused by the B 1B1 X 1A1 transition of H2CCC (l-C3H2). The large widths of the
bands are due to th...
Spatially Resolved Star Formation History Along the Disk of M82 Using Multi-Band Photometric Data

2010/11/12
We present the results on the star formation history and extinction in the disk of M82 over
spatial scales of 10′′ (180 pc). Multi-band photometric data covering from the far ultraviolet to the near...
