The LTHE LUMINOSITY, MASS, AND AGE DISTRIBUTIONS OF COMPACT STAR CLUSTERS IN M83 BASED ON HUBBLE SPACE TELESCOPE/WIDE FIELD CAMERA 3 OBSERVATIONS
filters binning
2014/12/20
The newly installed Wide Field Camera 3 (WFC3) on the Hubble Space Telescope has been used to obtain multi-band images of the nearby spiral galaxy M83. These new observations are the deepest and highe...
IDENTIFICATION OF A COMPLETE 160 μm FLUX-LIMITED SAMPLE OF INFRARED GALAXIES IN THE ISO LOCKMAN HOLE 1 deg2 DEEP FIELDS: SOURCE PROPERTIES AND EVIDENCE FOR STRONG EVOLUTION IN THE FIR LUMINOSITY FUNCTION FOR ULIRGs
starburst-active galactic nucleus (AGN) composite AGN spectral types
2014/12/20
We have identified a complete, flux-limited (S 160>120 mJy) sample of 160 μm selected sources from Spitzer observations of the 1 deg2 Infrared Space Observatory (ISO) Deep Field region in the Lockman ...
An optical study of the faint end of the stellar luminosity function
Stars Photometric functions Multicolor metering Height of fuzzy Projection Molecular cloud
2014/12/9
We implement a new method by which to study the faint end of the field star luminosity function. The method relies on deep, multicolor photometry of fields projected against highly obscured, nearby mo...
A Bayesian Approach to Calibrating Period-Luminosity Relations of RR Lyrae Stars in the Mid-Infrared
statistical methods RR Lyrae distance scale
2012/2/23
A Bayesian approach to calibrating period-luminosity (PL) relations has substantial benefits over generic least-squares fits. In particular, the Bayesian approach takes into account the full prior dis...
A Mid-Infrared Indicator for Total Infrared Luminosity and Star Formation Rate of Local and High-Redshift Galaxies
Indicator Total Infrared Luminosity High-Redshift Galaxies
2011/10/9
We present a new method to use 24 micron observations to estimate the total infrared luminosity, LIR, and the star formation rate of star-forming galaxies across the redshift range 0 < z < 3. This is ...
Segue 3: An Old, Extremely Low luminosity Star Cluster in the Milky Way's Halo
Extremely luminosity Star Cluster Milky Way
2011/10/10
We investigate the kinematic and photometric properties of the Segue 3 Milky Way companion using Keck/DEIMOS spectroscopy and Magellan/IMACS g and r-band imaging. Using maximum likelihood methods to a...
Early Black Holes in Cosmological Simulations: Luminosity Functions and Clustering Behaviour
quasars: general — galaxies: active — black hole physics — methods: numerical — galaxies: haloes
2011/9/29
We examine predictions for the quasar luminosity functions (QLF) and quasar clustering at high redshift (z > 4.75) using MassiveBlack, our new hydrodynamic cosmological simulation which includes a sel...

Eegular Articles Galaxy Luminosity Function: A New Analytic Expression
a new analytic approximation the luminosity function of galaxies the Schechter function
2010/10/19
We propose a new analytic approximation for the luminosity function of galaxies. The suggested expression behaves like the Schechter function at the faint end (φ ∼ Lα) but departs considerably a...
