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...
THE SPITZER LOCAL VOLUME LEGACY: SURVEY DESCRIPTION AND INFRARED PHOTOMETRY
surveys photometry
2014/12/22
The survey description and the near-, mid-, and far-infrared flux properties are presented for the 258 galaxies in the Local Volume Legacy (LVL). LVL is a Spitzer Space Telescope legacy program that s...
Using infrared photometry from the Spitzer Space Telescope, we perform the first inventory of aromatic feature emission (also commonly referred to as polycyclic aromatic hydrocarbon emission) for a st...

2011/1/11
An ultra-high-energy cosmic ray (UHECR) colliding with the Earth's atmosphere gives rise to an Extensive Air Shower (EAS). Due to different charge separation mechanisms within the thin shower front co...
The H-alpha Luminosity Function and Star-Formation Rate Volume Density at z=0.8 from the NEWFIRM H-alpha Survey
galaxies photometry — galaxies emission lines — galaxies distances and redshifts — galaxies
2010/11/15
We present new measurements of the H luminosity function (LF) and star-formation rate (SFR)
volume density for galaxies at z ∼ 0.8. Our analysis is based on 1.18μm narrowband data from
the NE...
We apply the nonstandard loop quantum cosmology method to quan-tize a flat FRW cosmological model with a free scalar field and the cosmological constant Λ > 0. Modification of the Hamiltonian in terms...
More galaxies in the Local Volume imaged in H-alpha
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We have carried out an H-alpha flux measurement for 52 nearby galaxies as part of a general H-alpha imaging survey for the Local Volume sample of galaxies within 10 Mpc. Most of the objects are probab...
Where are the Fossils of the First Galaxies? I. Local Volume Maps and Properties of the Undetected Dwarfs
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
We present a new method for generating initial conditions for LCDM N-body simulations which provides the dynamical range necessary to follow the evolution and distribution of the fossils of the first ...
