Photoionization of the Composite Nebula Surrounding NGC 5408 X-1: Implications for Beamed Emission
Jing Guo, Hua Feng, Roberto Soria +4
NGC 5408 X-1 is one of the best studied ultraluminous X-ray sources (ULXs) and is surrounded by a photoionized nebula. Previous optical spectroscopy established the presence of str…
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…
Radio counterparts of ultraluminous X-ray sources in nearby galaxies
Yijia Zhang, Hua Feng, Ailing Wang +1
Radio surveys of ultraluminous X-ray sources (ULXs) allow us to find supercritically accreting compact objects (SS 433/W50 like systems) or stripped nuclear black holes in nearby g…
The Complex Multi-Wavelength Morphology of the Peculiar Compact Galaxy Group IC 2431
Beverly J. Smith, Roberto Soria, Douglas Swartz +3
We present new Chandra X-ray imaging spectroscopy of the compact galaxy group IC 2431, and compare with archival ultraviolet, optical, infrared, and radio images. IC 2431 is a star…
The miniJPAS Survey: The radial distribution of star formation rates in faint X-ray active galactic nuclei
Nischal Acharya, Silvia Bonoli, Mara Salvato +35
We study the impact of black hole nuclear activity on both the global and radial star formation rate (SFR) profiles in X-ray-selected active galactic nuclei (AGN) in the field of m…
The supergiant optical counterpart of ULX P13 in NGC7793
C. Motch, M. W. Pakull, F. Grisé +1
We have identified the optical counterpart of the ULX source P13 in the nearby spiral galaxy NGC 7793. The object is a V ~ 20.5 mag star, ten times brighter than any other establis…
