STAR FORMATION RATES IN LYMAN BREAK GALAXIES: RADIO STACKING OF LBGs IN THE COSMOS FIELD AND THE SUB-mu Jy RADIO SOURCE POPULATION
formation evolution
2014/12/23
We present an analysis of the radio properties of large samples of Lyman break galaxies (LBGs) at z ~ 3, 4, and 5 from the COSMOS field. The median stacking analysis yields a statistical detection of ...
COMPARISON OF H alpha AND UV STAR FORMATION RATES IN THE LOCAL VOLUME: SYSTEMATIC DISCREPANCIES FOR DWARF GALAXIES
evolution dwarf
2014/12/23
Using a complete sample of ~300 star-forming galaxies within 11 Mpc of the Milky Way, we evaluate the consistency between star formation rates (SFRs) inferred from the far ultraviolet (FUV) non-ionizi...
DUST-CORRECTED STAR FORMATION RATES OF GALAXIES. I. COMBINATIONS OF H alpha AND INFRARED TRACERS
ISM evolution
2014/12/22
We combine Hα emission-line and infrared (IR) continuum measurements of two samples of nearby galaxies to derive dust attenuation-corrected star formation rates (SFRs). We use a simple energy balance ...
Five Supernova Survey Galaxies in the Southern Hemisphere: Supernova Ia Rates
supernovae: general galaxies:general galaxies: stellar content
2011/10/9
Based on the database with 56 SN events discovered in 3838 galaxies of the southern hemisphere, we compute the rate of supernovae (SNe) of different types along the Hubble sequence normalized to the o...
The Effect of Screening Factors and Thermonuclear Reaction Rates in the Pre-main Sequence Evolution of Low Mass Stars
Low mass stars thermonuclear reaction rates electron screening factors composition changes
2010/9/15
In understanding the nucleosynthesis of the elements in stars,one of the most important quantities is the reaction rate and it must be evaluated in terms of the stellar temperature T , and its determi...
