The PAH Emission Deficit In Low-Metallicity Galaxies - A Spitzer View
B. O'Halloran, S. Satyapal, R. P. Dudik
Archival observations of 18 starburst galaxies that span a wide range in metallicity reveal for the first time a correlation between the ratio of emission line fluxes of [FeII] at…
ISO observations of the interacting galaxy Markarian 297: with the powerful supernova remnant 1982aa
L. Metcalfe, B. O'Halloran, B. McBreen +10
Markarian (Mkn) 297 is a complex system with two interacting galaxies. Observations were made with ISO using ISOCAM, ISOPHOT and LWS. We present ISOCAM maps at 6.7, 7.7, 12 and 14.…
The Link Between Star Formation and Accretion in LINERs: A Comparison with other AGN Subclasses
S. Satyapal, R. P. Dudik, B. O'Halloran +1
We present archival high resolution X-ray imaging observations of 25 nearby LINERs observed by ACIS on board Chandra. This sample builds on our previously published proprietary and…
ISO observations of the Wolf-Rayet galaxies NGC 5430, NGC 6764, Mrk 309 and VII Zw 19
B. O'Halloran, B. McBreen, L. Metcalfe +2
Observations of four WR galaxies (NGC 5430, NGC 6764, Mrk 309 and VII Zw 19) using the Infrared Space Observatory are presented here. ISOCAM maps of NGC 5430, Mrk 309 and NGC 6764…
