Dual perspectives on GX 17+2: a simultaneous NICER and NuSTAR study
Malu Sudha, Renee M. Ludlam, Jeroen Homan +3
We performed the first simultaneous NICER & NuSTAR spectral and timing study of the Sco-like Z source GX 17+2. The source traced the full Z track during four observations. We detec…
Observational Astrophysics Research through Cross Institutional Research Partnerships
Kristen C. Dage, Linda Strubbe, Rhianna Taub +16
Undergraduate research in STEM can be a transformative experience, especially for Community College students, many of whom come from under-represented backgrounds. However, undergr…
The Structure of the Relativistic Fe Line in GX 340+0 as Viewed with XRISM/Resolve, NICER, and NuSTAR
R. M. Ludlam, R. Ballhausen, P. Chakraborty +13
We present a 152 ks XRISM/Resolve observation of the persistently accreting Z source GX 340+0. Simultaneous observations also occurred with NuSTAR and NICER for 22.47 ks and 2.7 ks…
Radio Continuum Studies of Ultra-Compact and Short Orbital Period X-Ray Binaries
Kristen C. Dage, Teresa Panurach, Kwangmin Oh +14
We present the radio continuum counterparts to the enigmatic ultra-compact X-ray binaries (UCXBs); a black hole or neutron star accreting from a hydrogen-deficient white dwarf dono…
