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…
Investigating MAXI J1752-457 with NuSTAR in the aftermath of a superburst
Sean N. Pike, Hitoshi Negoro, Douglas Buisson +5
We present two NuSTAR observations of the X-ray transient, MAXI J1752-457, following a superburst which was observed by MAXI/GSC in November, 2024. NuSTAR follow-up confirmed that…
Citizen CATE 2024: Extending Totality During the 8 April 2024 Total Solar Eclipse with a Distributed Network of Community Participants
Sarah A. Kovac, Amir Caspi, Daniel B. Seaton +240
The Citizen CATE 2024 next-generation experiment placed 43 identical telescope and camera setups along the path of totality during the total solar eclipse (TSE) on 8 April 2024 to…
Comprehensive Radio Monitoring of the Black Hole X-ray Binary Swift J1727.81613 during its 20232024 Outburst
Andrew K. Hughes, Francesco Carotenuto, Thomas D. Russell +39
This work presents comprehensive multi-frequency radio monitoring of the black hole low-mass X-ray binary Swift J1727.81613, which underwent its first recorded outburst after it…
Reprocessing from highly ionized gas in the soft spectral state of V4641 Sgr with NuSTAR
Riley M. T. Connors, Joey Neilsen, Aarran W. Shaw +6
V4641 Sgr is a low-mass black hole X-ray binary system with somewhat puzzling spectral characteristics during its soft state. Recent high-resolution spectroscopic studies of V4641…
