An Unusual Change in the Radio Jets of GRS 1915+105
Luis F. Rodriguez, I. Felix Mirabel
We compare Very Large Array observations of GRS 1915+105 made in 1994 and 2023, with nearly three decades of difference. The source has experienced intriguing major changes. The po…
Black Hole High Mass X-ray Binary Microquasars at Cosmic Dawn
I. F. Mirabel
Theoretical models and observations suggest that primordial Stellar Black Holes (Pop-III-BHs) were prolifically formed in HMXBs, which are powerful relativistic jet sources of sync…
Black holes formed by direct collapse: observational evidences
I. F. Mirabel
Binary black holes as the recently detected sources of gravitational waves can be formed from massive stellar binaries in the field or by dynamical interactions in clusters of high…
Stellar progenitors of black holes: insights from optical and infrared observations
I. F. Mirabel
Here are reviewed the insights from observations at optical and infrared wavelengths for low mass limits above which stars do not seem to end as luminous supernovae. These insights…
The Formation of Stellar Black Holes
I. F. Mirabel
It is believed that stellar black holes (BHs) can be formed in two different ways: Either a massive star collapses directly into a BH without a supernova (SN) explosion, or an expl…
Enhanced X-ray emission from Lyman Break Analogues and a Possible --SFR--Metallicity Plane
Matthew Brorby, Philip Kaaret, Andrea Prestwich +1
The source of energetic photons that heated and reionized the early Universe remains uncertain. Early galaxies had low metallicity and recent population synthesis calculations sugg…
