Compact stellar systems in the Fornax cluster: a UV perspective (2008)
Mieske, Steffen, Hilker, Michael, Bomans, Dominik J., Rey, Soo-Chang, Kim, Suk, Yoon, Suk-Jin, ...
In recent years, increasing evidence for chemical complexity and multiple stellar populations in massive globular clusters (GCs) has emerged, including extreme horizontal branches (EHBs) and UV...
An optical search for Low Surface Brightness Galaxies in the Arecibo HI Strip Survey (2006)
Trachternach, Clemens, Bomans, Dominik J., Haberzettl, Lutz, Dettmar, Ralf-Juergen
In order to estimate the contribution of low surface brightness (LSB) galaxies to the local (z18" at the limiting surface brightness of mu_{B,lim}=25.2+-0.31 mag/arcsec^2. Of these 306 galaxies, 148...
To see or not to see a Bow Shock: Identifying Bow Shocks with H-Alpha Allsky Surveys (2005)
Brown, Daniel, Bomans, Dominik J.
OB-stars have the highest luminosities and strongest stellar winds of all stars, which enables them to interact strongly with their surrounding ISM, thus creating bow shocks. These offer us an ideal...
A spectroscopic event of eta Car viewed from different directions: The data and first results (2005)
Stahl, Otmar, Weis, Kerstin, Bomans, Dominik J., Davidson, Kris, Gull, Theodore R., Humphreys, Roberta M.
We present spectroscopic observations with high spectral resolution of eta Car as seen by the SE lobe of the Homunculus nebula over the 2003.5 "spectroscopic event". The observed spectra represent...
Cannon, John M., Skillman, Evan D., Sembach, Kenneth R., Bomans, Dominik J.
We present new Far Ultraviolet Spectroscopic Explorer (FUSE) spectroscopy of the dwarf starburst galaxy NGC 625. These observations probe multiple phases of the interstellar medium (ISM), including...
Weis, Kerstin, Stahl, Otmar, Bomans, Dominik J., Davidson, Kris, Gull, Theodore R., Humphreys, Roberta M.
We present high spectral resolution echelle observations of the Balmer line variations during the 2003.5 ``spectroscopic event'' of eta Carinae. Spectra have been recorded of both eta Carinae and the...
SN2002kg -- the brightening of LBV V37 in NGC 2403 (2004)
Weis, Kerstin, Bomans, Dominik J.
SN2002kg is a type IIn supernova, detected in October 2002 in the nearby spiral galaxy NGC 2403. We show that the position of SN2002kg agrees within the errors with the position of the LBV V37....
Cannon, John M., Skillman, Evan D., Sembach, Kenneth R., Bomans, Dominik J.
We present new FUSE spectroscopy of the dwarf starburst galaxy NGC 625. These observations probe multiple phases of the interstellar medium, including the coronal, ionized, neutral and molecular gas....
BVR photometry of the resolved dwarf galaxy Ho IX (2004)
Georgiev, Tsvetan B., Bomans, Dominik J.
We present BVR CCD photometry down to limiting magnitude B=23.5 mag for 232 starlike objects and 11 diffuse objects in a 5.4' x 5.4' field of Ho IX. The galaxy is a gas-rich irregular dwarf galaxy...
A spectral and spatial analysis of eta Carinae's diffuse X-ray emission using CHANDRA (2003)
Weis, Kerstin, Corcoran, Michael F., Bomans, Dominik J., Davidson, Kris
The luminous unstable star (star system) eta Carinae is surrounded by an optically bright bipolar nebula, the Homunculus and a fainter but much larger nebula, the so-called outer ejecta. As images...
Cannon, John M., Dohm-Palmer, Robbie C., Skillman, Evan D., Bomans, Dominik J., Cote, Stephanie, Miller, Bryan W.
New HST/WFPC2 imaging of the dwarf starburst galaxy NGC 625 is presented. These data, 80% complete to V and I magnitudes of 26.0 and 25.3, respectively, allow us to study the recent star formation...
Feedback of massive stars on the ISM: a XMM-Newton view of the LMC superbubble N 51D (2003)
Bomans, Dominik J., Rossa, Jörn, Weiss, Kerstin, Dennerl, Konrad
An outflow from the nebula around the LBV candidate S 119 (2002)
Weis, Kerstin, Duschl, Wolfgang J., Bomans, Dominik J.
We present an analysis of the kinematic and morphological structure of the nebula around the LMC LBV candidate S 119. On HST images, we find a predominantly spherical nebula which, however, seems to...
The feedback of massive stars on the ISM: XMM-Newton view of the LMC superbubble N51D (2002)
Bomans, Dominik J., Rossa, Joern, Weis, Kerstin, Dennerl, Konrad
N51D (= DEM L 192) appears at first glance as a nearly circular, 120pc diameter bubble of ionized gas around the LMC OB association LH 54. A deeper look reveals a complex web of filaments and...
Warm and Hot Diffuse Gas in Dwarf Galaxies (2001)
Dwarf galaxies provide a special environment due to their low mass, small size and generally low metal content. These attributes make them perfect laboratories for the interaction of massive stars...
High velocity structures in, and the X-ray emission from the LBV nebula around Eta Carinae (2000)
Weis, Kerstin, Duschl, Wolfgang J., Bomans, Dominik J.
The Luminous Blue Variable star Eta Carinae is one of the most massive stars known. It underwent a giant eruption in 1843 in which the Homunculus nebula was created. ROSAT and ASCA data indicate the...
