Characterizing Distant Galaxies: Spectral Energy Distribution Analysis of X-ray Selected Star Forming Galaxies
galaxies - fundamental parameters Galaxies - high redshift Galaxies - submillimeter methods - statistical
2014/12/9
Comprehensive and robust analysis of galaxies found throughout cosmic time provides the means to probe the underlying characteristics of our Universe. Coupling observations and theory, spectral energy...
Extinction law in ultraluminous infrared galaxies at z ~ 1
dust, extinction — galaxies: evolution — galaxies: ISM — galaxies: starburst — infrared: galaxies — supernovae: general
2011/10/17
We analyze the multi-wavelength photometric and spectroscopic data of 12 ultraluminous infrared galaxies (ULIRGs) at z ~ 1 and compare them with models of stars and dust in order to study the extincti...
Narrow-line Seyfert 1 galaxies: an amasing class of AGN

2011/10/21
Narrow-line Seyfert 1 (NLS1) galaxies are a class of active galactic nuclei (AGN) that have all the properties of type 1 Seyfert galaxies but show peculiar characteristics, including the narrowest Bal...
A Search for Lyman Break Galaxies in the CDF-S Using Swift UVOT
Search Lyman Break Galaxies CDF-S Using Swift
2011/10/12
While the Swift satellite is primarily designed to study gamma-ray bursts, its ultraviolet and optical imaging and spectroscopy capabilities are also being used for a variety of scientific programs. I...
Astroinformatics of galaxies and quasars: a new general method for photometric redshifts estimation
cosmology: observations galaxies: redshifts methods: data mining surveys
2011/10/10
With the availability of the huge amounts of data produced by current and future large multi-band photometric surveys, photometric redshifts have become a crucial tool for extragalactic astronomy and ...
Keck Spectroscopy of Faint 3Galaxies:- Evidence for a Declining Fraction of Emission Line Sources In the Redshift Range 6
Keck Spectroscopy Declining Fraction Emission Line Sources
2011/9/29
Using deep Keck spectroscopy of Lyman break galaxies selected from infrared imaging data taken with WFC3/IR onboard the Hubble Space Telescope, we present new evidence for a reversal in the redshift-d...
The bright end of the colour-magnitude relation of cluster galaxies
galaxies: clusters: general - galaxies: formation - galaxies: evolution
2011/9/27
We investigate the development of the red sequence (RS) of cluster galaxies by using a semi-analytic model of galaxy formation. Results show good agreement between the general trend of the simulated R...
