XMM-Newton Resolves Parsec-scale X-ray Jets in the PeVatron Microquasar V4641 Sgr
Naomi Tsuji, Caterina Tresoldi, Kaya Mori +34
The microquasar V4641 Sagittarii (V4641 Sgr) has recently been established as one of the most powerful Galactic PeV cosmic-ray accelerators (PeVatrons) through the detection of deg…
The Delay Time Distribution of Quasi-Periodic Eruptions
Margaret Shepherd, K. Decker French, Jason T. Hinkle +4
Quasi-periodic eruptions (QPEs) are quasi-periodic X-ray bursts observed in the nucleus of a galaxy. Multiple pieces of observational evidence link QPEs to tidal disruption events…
Comparison of X-ray Emission Properties of TDEs and Soft Flares from AGNs
Samaresh Mondal, K. Decker French, Jason T. Hinkle
X-ray flaring activity from active galactic nuclei (AGNs) may mimic the expected emission from tidal disruption events (TDEs), thus contaminating TDE searches. To compare X-ray emi…
Identifying Changing-Look AGN Transitions in Light Curve Data with the Zwicky Transient Facility
Margaret E. Verrico, K. Decker French, Vivienne F. Baldassare +10
Changing-Look AGN (CL-AGN) are AGN which transition between Seyfert types, challenging AGN unification models. Most CL-AGN have been identified via repeat spectroscopy, making it d…
STONKS first results: Long-term transients in the XMM-Newton Galactic plane survey
Robbie Webbe, E. Quintin, N. A. Webb +5
The study of astronomical transients at high energies provides insights into some of the most extreme physical events in the universe; however, carrying out their detection and fas…
FEADME: Fast Elliptical Accretion Disk Modeling Engine
Nicholas Earl, K. Decker French, Jason T. Hinkle +5
We present FEADME (Fast Elliptical Accretion Disk Modeling Engine), a GPU-accelerated Python framework for modeling broad Balmer-line emission using a relativistic elliptical accre…
Unveiling the soft X-ray source population towards the inner Galactic disk with XMM-Newton
Tong Bao, Gabriele Ponti, Frank Haberl +5
Across the Galactic disk lies a diverse population of X-ray sources, with the fainter end remaining poorly understood due to past survey sensitivity limits. We aim to classify and…
The very faint X-ray transient Swift J174610-290018 at the Galactic center
Giovanni Stel, Gabriele Ponti, Nathalie Degenaar +17
Very Faint X-ray Transients (VFXTs) are a class of X-ray binary systems that exhibit occasional outbursts with peak X-ray luminosities (L_X< 1e36 erg s^-1) much lower than typical…
Utilizing Maximum Variability to Discern TDE Emission from AGN Flares
Samaresh Mondal, K. Decker French
X-ray emission arising from active galactic nucleus (AGN) activity may potentially mimic the expected emission of tidal disruption events (TDEs). Ongoing and upcoming wide-field X-…
Radio Variability in Recently-Quenched Galaxies: The Impact of TDE or AGN Driven Outflows
K. Decker French, Kristina Nyland, Pallavi Patil +7
Outflows and jets launched from the nuclei of galaxies emit radio synchrotron emission that can be used to study the impact of accretion energy on the host galaxy. The decades-long…
A sample of ionised Fe line-emitting X-ray sources in the inner Galactic disc
Samaresh Mondal, Gabriele Ponti, Tong Bao +4
Previous studies suggest that the Galactic diffuse X-ray emission is composed of unresolved point sources, primarily mCVs. However, nearby mCVs have a much lower 6.7 keV line equiv…
New interpretation of the two hard X-ray sources IGR J17503-2636 and IGR J17507-2647
L. Sidoli, V. Sguera, P. Esposito +4
We report on the results of X-ray observations (XMM-Newton, INTEGRAL and Swift) of two hard X-ray sources, IGR J17503-2636 and IGR J17507-2647, whose nature is not fully elucidated…
XMM-Newton and NuSTAR discovery of a likely IP candidate XMMU J173029.8-330920 in the Galactic Disk
Samaresh Mondal, Gabriele Ponti, Luke Filor +7
We aim at characterizing the population of low-luminosity X-ray sources in the Galactic plane by studying their X-ray spectra and periodic signals in the light curves. We are perfo…
Periodicity from X-ray sources within the inner Galactic disk
Samaresh Mondal, Gabriele Ponti, Tong Bao +9
For many years, it has been claimed that the Galactic ridge X-ray emission at the Galactic Center (GC) is truly diffuse in nature. However, with the advancement of modern X-ray sat…
X-rays from a Central "Exhaust Vent" of the Galactic Center Chimney
Scott C. Mackey, Mark R. Morris, Gabriele Ponti +2
Using deep archival observations from the Chandra X-ray Observatory, we present an analysis of linear X-ray-emitting features located within the southern portion of the Galactic ce…
An intermediate polar candidate toward the Galactic plane
Samaresh Mondal, Gabriele Ponti, Frank Haberl +5
For the past decade, it has been suggested that intermediate polars (IPs), a subclass of magnetic cataclysmic variables (CVs), are one of the main contributors to the hard diffuse…
