Smith, Nathan, Whitney, Barbara A., Conti, Peter S., De Pree, Chris G., Jackson, James M.
We present high spatial resolution mid-IR images of the ring of UCHII regions in W49A obtained at Gemini North, allowing us to identify the driving source of its powerful H2O maser outflow. These...
Smith, Nathan, Conti, Peter S.
(abridged) We propose the new designation ``WNH'' for luminous Wolf-Rayet (WR) stars of the nitrogen sequence with H in their spectra. These are commonly called WNL stars (e.g., WN7h), but this new...
The stellar content of the WR galaxy NGC5253 from ISO/SWS spectroscopy (2007)
Paul A. Crowther, Sara C. Beck, Allan J. Willis, Peter S. Conti, Patrick W. Morris, Ralph S. Sutherland
1. Why mid-IR spectroscopy of WR galaxies? Wolf-Rayet (WR) galaxies are a subset of blue emission-line galaxies whose spectra show the signature of large numbers of WR stars with ages in the range
MSX Mid infrared imaging of massive star birth environments. II: Giant HII regions (2003)
Conti, Peter S, Crowther, Paul A.
We conduct a Galactic census of Giant HII regions, based on the all sky 6cm dataset of Kuchar & Clark, plus the kinematic distances obtained by Russeil. From an inspection of mid-IR Mid-course Space...
MSX Mid Infrared Imaging of Massive Star Birth Environments. I: Ultracompact HII Regions (2003)
Crowther, Paul A., Conti, Peter S.
We present mid-IR 21micron images of a sample of radio selected Ultracompact HII (UCHII) regions, obtained with the Midcourse Space Experiment (MSX). All, with one possible exception, are detected at...
N-band observations of Henize 2-10: Unveiling the dusty engine of a starburst galaxy (2002)
Vacca, William D., Johnson, Kelsey E., Conti, Peter S.
As part of an ongoing program to better understand the early stages of massive star cluster evolution and the physical conditions for their formation, we have obtained J, H, K', and N (10.8 mum)...
The early stages of extragalactic star cluster evolution: new results from Gemini (2002)
Johnson, Kelsey E., Vacca, William D., Conti, Peter S., Kobulnicky, Henry A.
MSX mid infrared imaging of massive star birth environments. I: Ultracompact H-II regions (2002)
Paul A. Crowther, Peter S. Conti
We present mid-IR 21m images of a sample of radio selected Ultracompact H ii (UCH ii) regions, obtained with the Midcourse Space Experiment (MSX). All, with one possible exception, are detected at...
N-band Observations of He 2-10: Unveiling the Dusty Engine of a Starburst Galaxy (2001)
Vacca, William D., Johnson, Kelsey E., Conti, Peter S.
To better understand the early stages of massive star cluster evolution we have obtained J,H,K', and N (10.8 micron) images of the nuclear region of the starburst galaxy He 2-10. The N-band images...
Massive Star Birth in the Inner Galaxy: Obscured Massive Star Clusters (2001)
Blum, Robert D., Conti, Peter S., Damineli, Augusto, Figueredo, Elysandra
The current census of, and stellar population in, massive Galactic star clusters is reviewed. In particular, we concentrate on a recent survey of obscured Galactic Giant H II (GHII) regions and the...
Near Infrared Observations of the Giant HII Region W49A: A Starbirth Cluster (2001)
Conti, Peter S., Blum, Robert D.
W49A is one of the most luminous giant H II (GH II) regions in our Galaxy. This star forming complex contains numerous compact and ultra-compact (UC) H II regions, extending over an area of 15 pc. It...
Properties of Hot Stars in the Wolf-Rayet galaxy NGC5253 from ISO Spectroscopy (1998)
Crowther, Paul A., Beck, S. C., Willis, Allan J., Conti, Peter S., Morris, Pat W., Sutherland, Ralph S.
ISO-SWS spectroscopy of the WR galaxy NGC5253 is presented, and analysed to provide estimates of its hot young star population. Our approach differs from previous investigations in that we are able...
HST Ultraviolet Spectroscopy of NGC 1741- a Nearby Template for Distant Energetic Starbursts (1996)
Conti, Peter S., Leitherer, Claus, Vacca, William D.
We have obtained a Hubble Space Telescope ultraviolet image and spectrum of the nearby Wolf-Rayet galaxy NGC 1741. The spatial morphology from the Faint Object Camera image is dominated by two main...
