An Atlas of Optical Continuum and Line Emission from Low-Mass X-Ray Binaries
Broadband optical spectra of a sample of 15 low-mass X-ray binaries (LMXBs) is obtained in the range of 4000-9000 A. The spectra are fitted with combinations of...
An X-Ray and Radio View of the 2022 Reactivation of the Magnetar SGR J1935+2154
Recently, the Galactic magnetar SGR J1935+2154 has garnered attention due to its emission of an extremely luminous radio burst, reminiscent of fast radio bursts...
Analysis of the Full Spitzer Microlensing Sample. I. Dark Remnant Candidates and Gaia Predictions
In the pursuit of understanding the population of stellar remnants within the Milky Way, we analyze the sample of ∼950 microlensing events observed by the...
Aql X-1 back in outburst: multi-wavelength observations
On November 1st. RXTE-PCA scans of the Aql region detected X-ray emission consistent with the neutron star transient and atoll source Aql X-1. Further scans and...
In July, the transient neutron star low-mass X-ray binary Aql X-1 was detected in outburst at X-ray, UV, optical and near-infrared wavelengths (ATel #2742,...
Aql X-1 transition towards the soft (banana) state accompanied by radio/NIR detection
The currently active neutron star transient and atoll source Aql X-1 (Linares et al., ATEL #2288) has begun the transition from the hard (extreme island) state...
Are Q-stars a serious threat for stellar-mass black hole candidates?
We examine the status of the threat posed to stellar-mass black hole candidates by the possible existence of Q-stars (compact objects with an exotic equation of...
