New constraints on the binary system HD 327083 and its gaseous and dusty environments

L. Cidale, P. Marchiano, M. Kraus +11

Binary systems with circumbinary molecular and dust rings are of great interest because they provide insights into the dynamics and evolution of stellar systems and the chemistry o…

Mare versus highland lunar impact flash light curve dichotomy

D. Athanasopoulos, A. Liakos, A. Z. Bonanos +5

We perform a comprehensive analysis of lunar impact flash (LIF) light curve shapes and their dependence on the lunar terrain, using the large sample of LIFs detected by NELIOTA ove…

CIV wind properties of the SDSS-V X-ray selected quasars: strong optical-to-UV emission is key regardless of X-ray strength

Amy L. Rankine, David Homan, James Aird +25

We present an investigation of the rest-frame optical/UV and X-ray properties for a sample of 3027 X-ray selected quasars between detected in the deepest Spec…

Black hole mass, host galaxy mass, and dark matter halos: Testing the environmental connection

G. Mountrichas, F. Shankar, F. J. Carrera +1

We investigate the connection between supermassive black holes (SMBHs), their host galaxies, and large-scale dark-matter halos using broad-line X-ray AGN from the XMM--XXL and Stri…

IZ Tel and UW Vir: Southern oscillating eclipsing Algol systems with active mass transfer

Alexios Liakos, David J. W. Moriarty, Julian F. West +1

This study is an in-depth examination of IZ Tel and UW Vir which are semi-detached oscillating Eclipsing Algol binary systems (oEA stars). The radial velocities of both components…

Accelerating scaling solutions from dark matter particle creation

Sudip Halder, Jaume de Haro, Supriya Pan +3

This article opens new window to obtain accelerating scaling attractors without any need of dark energy. We study cosmological dynamics in a two-fluid system where pressureless dar…
