A Multiwavelength Assessment Disfavoring the X-ray Binary Origin of He III Regions in Metal-Poor Star-Forming Dwarf Galaxies
Ivan Altunin, Christopher Ellis, Richard M. Plotkin +9
Recent observations of metal-poor, star-forming dwarf galaxies reveal He III regions, traced by nebular He II 4686 emission that require a strong source of extreme-ultraviolet (EUV…
A multiband look at ultraluminous X-ray sources in NGC 7424
Roberto Soria, Siying Cheng, Manfred W. Pakull +2
We studied the multiband properties of two ultraluminous X-ray sources (2CXO J225728.9-410211 = X-1 and 2CXO J225724.7-410343 = X-2) and their surroundings, in the spiral galaxy NG…
X-raying the galaxy pair Arp 41: no collision in NGC 1232 and three ultraluminous sources in NGC 1232A
Roberto Soria, Manfred W. Pakull
We studied the apparent galaxy pair NGC 1232 / NGC 1232A with Chandra, looking for evidence of interactions and collisions. We report that there is no cloud of diffuse emission in…
The ultraluminous X-ray source bubble in NGC 5585
Roberto Soria, Manfred Pakull, Christian Motch +4
Some ultraluminous X-ray sources (ULXs) are surrounded by collisionally ionized bubbles, larger and more energetic than supernova remnants: they are evidence of the powerful outflo…
Optical IFU spectroscopy of a bipolar microquasar jet in NGC 300
A. F. McLeod, S. Scaringi, R. Soria +9
We recently reported the discovery of a candidate jet-driving microquasar (S10) in the nearby spiral galaxy NGC 300. However, in the absence of kinematic information, we could not…
A newly discovered double-double candidate microquasar in NGC 300
R. Urquhart, R. Soria, M. W. Pakull +7
We present the discovery of a powerful candidate microquasar in NGC 300, associated with the S 10 optical nebula (previously classified as a supernova remnant). Chandra images show…
