We present an X-ray study of our nearest starburst galaxy IC 10, based on XMM–Newton and Chandra observations. A list of 73 XMM–Newton and 28 Chandra detections of point-like X-ray sources in the fiel...
Stars at the Tip of Peculiar Elephant Trunk-Like Clouds in IC 1848E: A Possible Third Mechanism of Triggered Star Formation
ISM: HII regions — ISM: individual (IC 1848E) — ISM: kinematics and dynamics — stars: formation — stars: pre-main-sequence
2011/10/10
The HII region IC 1848 harbors a lot of intricate elephant trunk-like structures that look morphologically different from usual bright-rimmed clouds (BRCs). Of particular interest is a concentration o...
Large-scale radio nebula around the Ultra-Luminous X-ray Source IC 342 X-1
Large-scale radio nebula the Ultra-Luminous X-ray Source IC 342 X-1
2011/1/10
We present discovery of a radio nebula associated with the ultraluminous X-ray source (ULX) IC 342 X-1 using the Very Large Array (VLA). Taking the surrounding nebula as a calorimeter, one can constra...
Deconvolution of Images from BLAST 2005: Insight into the K3-50 and IC 5146 Star-Forming Regions
BLAST 2005 the K3-50 IC 5146 Star-Forming Regions

Context. The investigations of the photometric and spectral variability of PMS stars are essential to a better understanding of the early phases of stellar evolution. We are carrying out a photometric...
Investigating the Cosmic-Ray Ionization Rate Near the Supernova Remnant IC 443 Through H3+ Observations
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/6
Observational and theoretical evidence suggests that high-energy Galactic cosmic rays are primarily accelerated by supernova remnants. If also true for low-energy cosmic rays, the ionization rate near...
The ionized gas at the center of IC 10: A possible localized chemical pollution by Wolf-Rayet stars
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We present results from integral field spectroscopy with the Potsdam Multi-Aperture Spectrograph at the 3.5m telescope at Calar Alto Observatory of the intense star-forming region [HL90] 111 at the ce...
MEASUREMENT OF THE LICK INDICES IN EARLY-TYPE GALAXIES: LINE-OF-SIGHT VELOCITY DISTRIBUTION CORRECTIONS FOR IC 1459
Line: profiles Methods: data analysis Galaxies: elliptical and lenticular, cD Galaxies: kinematics and dynamics Galaxies: individual (IC 1459)
2010/10/29
In this paper we analyse the measurements of the absorption line-strength Lick indices in the early-type galaxy IC 1459. We use the long-slit spectra of the elliptical galaxy IC 1459 from which its ki...
