The HII region G35.673-00.847: another case of triggered star formation?
The HII region G35.673-00.847 triggered star formation
2011/1/11
As part of a systematic study that we are performing with the aim to increase the observational evidence of triggered star formation in the surroundings of HII regions, we analyze the ISM around the H...
The Interplay of Magnetic Fields, Fragmentation and Ionization Feedback in High-Mass Star Formation
Magnetic Fields Fragmentation High-Mass Star Formation
2011/1/13
Massive stars disproportionately influence their surroundings. How they form has only started to become clear recently through radiation gas dynamical simulations. However, until now, no simulation ha...
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...
A simple connection between the near- and mid-infrared emission of galaxies and their star-formation rates
the near- and mid-infrared emission galaxies
2011/1/10
We have measured the near-infrared colors and the fluxes of individual pixels in 68 galaxies common to the Spitzer Infrared Nearby Galaxies Survey and the Large Galaxy Atlas Survey. Each galaxy was se...
ACCESS III: The Nature of Star Formation in the Shapley Supercluster
Star Formation the Shapley Supercluster
2011/1/10
We present a joint analysis of panoramic Spitzer/MIPS mid-infrared and GALEX ultraviolet imaging of the Shapley supercluster at z=0.048. Combining this with spectra of 814 supercluster members and 1.4...
ACCESS II: A Complete Census of Star Formation in the Shapley Supercluster - UV and IR Luminosity Functions
Star Formation the Shapley Supercluster - UV IR Luminosity Functions
2011/1/10
We present panoramic Spitzer/MIPS mid- and far-infrared and GALEX ultraviolet imaging of the the most massive and dynamically active system in the local Universe, the Shapley supercluster at z=0.048, ...
The Luminosity Problem: Testing Theories of Star Formation
The Luminosity Problem Testing Theories Star Formation
2011/1/10
Low-mass protostars are less luminous than expected. This luminosity problem is important because the observations appear to be inconsistent with some of the basic premises of star formation theory. T...
Star Formation in Collision Debris: Insights from the modeling of their Spectral Energy Distribution

2010/12/28
During galaxy-galaxy interactions, massive gas clouds can be injected into the intergalactic medium which in turn become gravitationally bound, collapse and form stars, star clusters or even dwarf gal...

2010/3/8
We analyse Spitzer MIPS 24micron observations, and SDSS (DR7) optical broadband photometry and spectra, to investigate the star formation (SF) properties of galaxies residing in the Coma supercluster ...
Cosmic star formation history revealed by the AKARI, & Spatially-resolved spectroscopy of an E+A (Post-starburst) system

2010/3/8
We reveal cosmic star-formation history obscured by dust using deep infrared observation with the AKARI. A continuous filter coverage in the mid-IR wavelength (2.4, 3.2, 4.1, 7, 9, 11, 15, 18, and 24u...
