RADIAL DISTRIBUTION OF STARS, GAS AND DUST IN SINGS GALAXIES. I. SURFACE PHOTOMETRY AND MORPHOLOGY
photometry fundamental parameters
font style='font-size:12px;'>
2014/12/23
We present ultraviolet through far-infrared (FIR) surface brightness profiles for the 75 galaxies in the Spitzer Infrared Nearby Galaxies Survey (SINGS). The imagery used to measure the profiles inclu...
Radial distribution of stars, gas and dust in SINGS galaxies II. DERIVED DUST PROPERTIES
dust extinction ISM
font style='font-size:12px;'>
2014/12/23
We present a detailed analysis of the radial distribution of dust properties in the SINGS sample, performed on a set of ultraviolet (UV), infrared (IR), and H I surface brightness profiles, combined w...
DYNAMIC S0 GALAXIES: A CASE STUDY OF NGC 5866
galaxies individual (NGC 5866)
font style='font-size:12px;'>
2014/12/23
S0 galaxies are often thought to be passively evolved from spirals after star formation is quenched. To explore what is actually occurring in such galaxies, we present a multi-wavelength case study of...
COMPARISON OF H alpha AND UV STAR FORMATION RATES IN THE LOCAL VOLUME: SYSTEMATIC DISCREPANCIES FOR DWARF GALAXIES

font style='font-size:12px;'>
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...
Galaxies in a simulated Lambda CDM Universe - I. Cold mode and hot cores

font style='font-size:12px;'>
2014/12/23
We study the formation of galaxies in a large volume (50 h−1 Mpc, 2 × 2883 particles) cosmological simulation, evolved using the entropy and energy-conserving smoothed particle hydrodynamics (SP...
Galaxies in a simulated Lambda CDM universe - II. Observable properties and constraints on feedback
feedback cluster
font style='font-size:12px;'>
2014/12/23
We compare the properties of galaxies that form in a cosmological simulation without strong feedback to observations of the z= 0 galaxy population. We confirm previous findings that models without str...
DUST-CORRECTED STAR FORMATION RATES OF GALAXIES. I. COMBINATIONS OF H alpha AND INFRARED TRACERS
ISM evolution
font style='font-size:12px;'>
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 ...
