Dissecting high-mass star-forming regions complex formation history
2011/8/24
We present near-infrared JHKs imaging as well as K-band multi-object spectroscopy of the massive stellar content of W3 Main using LUCI at the LBT. We confirm 13 OB stars by their absorption line spect...
The Stellar Archeology of the M33 Disk: Recent Star-Forming History and Constraints on the Timing of an Interaction with M31
galaxies evolution — galaxies spiral — galaxies
2011/8/24
Images recorded with MegaCam are used to investigate the recent star-forming history (SFH) of the Local Group Sc galaxy M33. The properties of the stellar disk change near R = 8 kpc. Within this radiu...
The Mid-Infrared High-Ionization Lines from Active Galactic Nuclei and Star-Forming Galaxies
The Mid-Infrared High-Ionization Lines Active Galactic Nuclei Star-Forming Galaxies
2011/1/10
We used Spitzer/IRS spectroscopic data on 426 galaxies including quasars, Seyferts, LINER and HII galaxies to investigate the relationship among the mid-IR emission lines. There is a tight linear corr...
Deconvolution of Images from BLAST 2005: Insight into the K3-50 and IC 5146 Star-Forming Regions

Chandra Observation the Obscured Star-Forming Complex W40
2011/1/11
The young stellar cluster illuminating the W40 H II region, one of the nearest massive star forming regions, has been observed with the ACIS detector on board the Chandra X-ray Observatory. Due to its...
The chemical composition of the Orion star-forming region: II. Stars, gas, and dust: the abundance discrepancy conundrum
the Orion star-forming region II. Stars
2011/1/13
We re-examine the recombination/collisional emission line (RL/CEL) nebular abundance discrepancy problem in the light of recent high-quality abundance determinations in young stars in the Orion star-f...
Short-lived star-forming giant clumps in cosmological simulations of z~2 disks

2010/11/9
Many observed massive star-forming z ≈ 2 galaxies are large disks that exhibit irregular morphologies, with ≈ 1 kpc, ≈ 108-10M⊙ clumps. We present high-resolution cosmological SPH simulations that zoo...
Assessing Radiation Pressure as a Feedback Mechanism in Star-Forming Galaxies

2010/11/10
Radiation pressure from the absorption and scattering of starlight by dust grains may be an important feedback mechanism in regulating star-forming galaxies. We compile data from the literature on sta...
