A cooler look at the environment of Cygnus X-1: Searching for dynamical interactions within cold molecular gas
Pau Bosch-Cabot, Alexandra J. Tetarenko, Valentí Bosch-Ramon +7
We present IRAM--30m observations aimed at identifying potential outflow-interstellar medium interaction sites in the vicinity of the black hole X-ray binary Cygnus X--1, which dis…
Optical outburst evolution of the transient black hole X-ray binary Swift J1727.8-1613: Disc response to jet ejections and late-outburst emergence of powerful disc winds
N. Castro Segura, K. Solomons, J. M. Corral-Santana +22
Swift J1727.81613 is a newly discovered transient low-mass X-ray binary harbouring a stellar-mass () black hole. We present state-resolved VLT/X-Shooter optical…
Chlorine and Potassium Enrichment in the Cassiopeia A Supernova Remnant
XRISM collaboration
The elements in the universe are synthesized primarily in stars and supernovae, where nuclear fusion favors the production of even-Z elements. In contrast, odd-Z elements are less…
XRISM Observations of Accretion Disk Corona in Cyg X-2
Misaki Mizumoto, Hiromitsu Takahashi, Ehud Behar +6
We present the high-resolution X-ray spectrum of the Z-source Cygnus X-2, obtained with X-Ray Imaging and Spectroscopy Mission (XRISM). The observations have enabled a precise char…
The Feasibility of Using Fe XXIII Metastable Transitions as a Density Diagnostic for LMXB Disk Winds
D. L. Moutard, L. R. Corrales, R. Tomaru +6
Low mass X-ray binaries (LMXBs) occasionally show signs of outflowing material from the accretion disk. Studying these outflows can inform the understanding of the geometry of the…
Overionized plasma in the supernova remnant Sagittarius A East anchored by XRISM observations
XRISM Collaboration
Sagittarius A East is a supernova remnant with a unique surrounding environment, as it is located in the immediate vicinity of the supermassive black hole at the Galactic center, S…
Discovery of a thermonuclear Type I X-ray burst in infrared: new limits on the orbital period of 4U 1728-34
F. M. Vincentelli, Y. Cavecchi, P. Casella +4
We report the detection of an infrared burst lagging a thermonuclear Type I X-ray burst from the accreting neutron star 4U 1728-34 (GX 354-0). Observations were performed simultane…
The Voyage of Metals in the Universe from Cosmological to Planetary Scales: the need for a Very High-Resolution, High Throughput Soft X-ray Spectrometer
F. Nicastro, J. Kaastra, C. Argiroffi +27
Metals form an essential part of the Universe at all scales. Without metals we would not exist, and the Cosmos would look completely different. Metals are primarily born through nu…
Discovery of millihertz quasi-periodic oscillations in the X-ray binary EXO 0748--676
G. C. Mancuso, D. Altamirano, F. García +5
We report the discovery of millihertz quasi-periodic oscillations (mHz QPOs) from the bursting, high-inclination atoll neutron-star low-mass X-ray binary (NS LMXB) EXO 0748--676 wi…
The cooling, mass and radius of the neutron star in EXO 0748-676 in quiescence with XMM-Newton
Zheng Cheng, Mariano Mendez, Maria Diaz-Trigo +1
We analyse four XMM-Newton observations of the neutron-star low-mass X-ray binary EXO 0748676 in quiescence. We fit the spectra with an absorbed neutron-star atmosphere model, w…
Systematic Uncertainties in the Spectroscopic Measurements of Neutron-Star Masses and Radii from Thermonuclear X-ray Bursts. III. Absolute Flux Calibration
Tolga Guver, Feryal Ozel, Herman Marshall +3
Many techniques for measuring neutron star radii rely on absolute flux measurements in the X-rays. As a result, one of the fundamental uncertainties in these spectroscopic measurem…
Irregular time series in astronomy and the use of the Lomb-Scargle periodogram
R. Vio, M. Diaz-Trigo, P. Andreani
Detection of a signal hidden by noise within a time series is an important problem in many astronomical searches, i.e. for light curves containing the contributions of periodic/sem…
Distribution and Structure of Matter in and around Galaxies
Norbert S. Schulz, Glenn Allen, Mark W. Bautz +24
Understanding the origins and distribution of matter in the Universe is one of the most important quests in physics and astronomy. Themes range from astro-particle physics to chemi…
