From a mountain high in Chile's Atacama Desert, astronomers at the U.S. National Science Foundation's Atacama Cosmology Telescope (ACT) have taken a fresh look at the oldest light in th...

A faint blue galaxy about 30 million light-years from Earth and located in the constellation Leo Minor could shed new light on conditions at the birth of the universe.Astronomers at Indiana University...
On the evolutionary history of stars and their fossil mass and light

2014/12/23
The total extragalactic background radiation can be an important test of the global star formation history (SFH). Using direct observational estimates of the SFH, along with standard assumptions about...
Cosmologists have made the most sensitive and precise measurements yet of the polarization of the cosmic microwave background.
The report, published October 20 in the Astrophysical Journal, marks an ...

Stellar mass-to-light ratio gradients in galaxies: correlations with mass
dark matter – galaxies : evolution – galaxies : galaxies : general –galaxies : elliptical and lenticular, cD.
2011/10/9
We analyze the stellar mass-to-light ratio (M/L) gradients in a large sample of local galaxies taken from the Sloan Digital Sky Survey, spanning a wide range of stellar masses and morphological types....
Is light neutralino as dark matter still viable?
Galaxies: clusters: general intracluster medium Radio continuum: galaxies Radio telescopes
2011/9/29
Motivated by the recent re-confirmation by CoGENT of the low-energy excess of events observed last year, and the recent improved limits from the XENON-100 experiment that are in contention with the Co...
Light propagation and the average expansion rate in near-FRW universes
Light propagation average expansion rate universes
2011/9/29
We consider universes which are close to Friedmann-Robertson-Walker in the sense that metric perturbations, their time derivatives and first spatial derivatives are small, but second spatial derivativ...
Confronting 2D delayed-detonation models with light curves and spectra of Type Ia supernovae
supernovae: general
2011/9/26
We compare models for Type Ia supernova (SN Ia) light curves and spectra with an extensive set of observations. The models come from a recent survey of 44 two-dimensional delayed-detonation models com...
