Comprehensive X-ray Study of Giant Radio Galaxies with XMM-Newton and Chandra
Niraj Maurya, Satish S. Sonkamble, Suraj Dhiwar +3
The paper presents a systematic X‑ray spectral analysis of 27 giant radio galaxies using archival XMM‑Newton and Chandra observations, examining nuclear absorption, Fe Kα emission,…
Revealing the Physical Driver of the Baldwin Effect: Gas Density in the Broad-Line Region
Wen-Qiang Liang, Zhi-Fu Chen, Rui-Jing Lu +8
The paper shows that the Baldwin effect in quasars is mainly driven by the gas density in the broad-line region, with higher Eddington ratios producing denser BLRs and shallower eq…
High-mass binary black hole mergers from detailed binary evolution models
Max M. Briel, Olcay Bıyıklı, Tassos Fragos +10
The paper uses detailed binary evolution simulations to test whether super‑Eddington mass transfer in isolated binaries can produce the observed high‑mass binary black hole mergers…
JWST/MIRI Detection of Molecular H Winds from an Edge-on Class II Source HV Tau C
Vinod Chandra Pathak, P. Manoj, Himanshu Tyagi +14
The paper uses JWST/MIRI mid‑infrared spectroscopy to detect and characterize a wide‑angled molecular hydrogen wind from the edge‑on Class II protoplanetary disk HV Tau C, measurin…
A discussion on the symmetry of relativistic Vlasov gas and its accretion in Kerr-Newman black hole
Yongqiang Liu
The paper studies how a collisionless Vlasov gas behaves around a Kerr‑Newman black hole, deriving analytic expressions for the distribution function, accretion rates and anisotrop…
I Can Do It With A Broken Planetesimal: Characterising the planetary debris in heavily polluted cool white dwarfs
Anna-Maria Cutolo, Boris T. Gänsicke, Boris T. Gänsicke +8
The paper analyzes four cool, metal‑polluted hydrogen‑atmosphere white dwarfs using X‑shooter spectra to determine their atmospheric parameters and the composition of accreted plan…
