Detection of extended X-ray emission around the PeVatron microquasar V4641 Sgr with XRISM
Hiromasa Suzuki, Naomi Tsuji, Yoshiaki Kanemaru +26
A recent report on the detection of very-high-energy gamma rays from V4641 Sagittarii (V4641 Sgr) up to ~0.8 peta-electronvolt has made it the second confirmed "PeVatron" microquas…
NuSTAR broadband X-ray observation of EF Eri following its reawakening into a high accretion state
Luke W. Filor, Kaya Mori, Gabriel Bridges +7
We present the first NuSTAR X-ray observation of EF Eri, a well-known polar system. The NuSTAR observation was conducted in conjunction with NICER, shortly after EF Eri entered a h…
Spectrum and location of ongoing extreme particle acceleration in Cassiopeia A
Jooyun Woo, Kaya Mori, Charles J. Hailey +8
Young supernova remnants (SNRs) are believed to be the origin of energetic cosmic rays (CRs) below the "knee" of their spectrum at petaelectronvolt (PeV, eV). Nev…
Detection of X-ray Emission from a Bright Long-Period Radio Transient
Ziteng Wang, Nanda Rea, Tong Bao +46
Recently, a class of long-period radio transients (LPTs) has been discovered, exhibiting emission on timescales thousands of times longer than radio pulsars. Several models had bee…
Investigation of the non-thermal X-ray emission from the supernova remnant CTB 37B hosting the magnetar CXOU J171405.7381031
Chanho Kim, Jaegeun Park, Hongjun An +4
We present a detailed X-ray investigation of a region (S1) exhibiting non-thermal X-ray emission within the supernova remnant (SNR) CTB 37B hosting the magnetar CXOU J171405.738…
A Broadband X-ray Investigation of Fast-Spinning Intermediate Polar CTCV J2056-3014
Ciro Salcedo, Kaya Mori, Gabriel Bridges +5
We report on XMM-Newton, NuSTAR, and NICER X-ray observations of CTCV J2056-3014, a cataclysmic variable (CV) with one of the fastest-spinning white dwarfs (WDs) at P = 29.6 s. Whi…
Cataclysmic Variables and AM CVn Binaries in SRG/eROSITA + Gaia: Volume Limited Samples, X-ray Luminosity Functions, and Space Densities
Antonio C. Rodriguez, Kareem El-Badry, Valery Suleimanov +22
We present volume-limited samples of cataclysmic variables (CVs) and AM CVn binaries jointly selected from SRG/eROSITA eRASS1 and \textit{Gaia} DR3 using an X-ray + optical color-c…
