TYC 3340-2437-1: A Quadruple System with A Massive Star
Jiao Li, Chao Liu, Changqing Luo +10
Hierarchical massive quadruple systems are ideal laboratories for examining the theories of star formation, dynamical evolution, and stellar evolution. The successive mergers of hi…
The weakness of soft X-ray intensity: possible physical reason for weak line quasars
Jiancheng Wu, Qingwen Wu, Chichuan Jin +8
Weak-line quasars (WLQs) are a notable group of active galactic nuclei (AGNs) that show unusually weak UV lines even though their optical-UV continuum shapes are similar to those o…
Wavelength Dependences of the Optical/UV and X-ray Luminosity Correlations of Quasars
Chichuan Jin, Elisabeta Lusso, Martin Ward +2
The inter-band correlations between optical/UV and X-ray luminosities of active galactic nuclei (AGN) are important for understanding the disc-coronal connection, as well as using…
Constraints on the ultra-fast outflows in the narrow-line Seyfert 1 galaxy Mrk 1044 from high-resolution time- and flux-resolved spectroscopy
Yerong Xu, Ciro Pinto, Daniele Rogantini +5
Ultra-fast outflows (UFOs) have been revealed in a large number of active galactic nuclei (AGN) and are regarded as promising candidates for AGN feedback on the host galaxy. The na…
Study of the excess Fe XXV line emission in the central degrees of the Galactic centre using XMM-Newton data
K. Anastasopoulou, G. Ponti, M. C. Sormani +14
The diffuse Fe XXV (6.7 keV) line emission observed in the Galactic ridge is widely accepted to be produced by a superposition of a large number of unresolved X-ray point sources.…
The radio detection and accretion properties of the peculiar nuclear transient AT 2019avd
Yanan Wang, Ranieri D. Baldi, Santiago del Palacio +19
AT 2019avd is a nuclear transient detected from infrared to soft X-rays, though its nature is yet unclear. The source has shown two consecutive flaring episodes in the optical and…
