A systematic study of the advection-dominated accretion flow for the origin of the X-ray emission in weakly magnetized low-level accreting neutron star
Erlin Qiao, B. F. Liu
Observationally, the X-ray spectrum ( keV) of low-level accreting neutron stars (NSs) can generally be well fitted by the model with two components, i.e, a thermal soft X-r…
The Large Amplitude X-ray Variability in NGC 7589: Possible Evidence for Accretion Mode Transition

We report the discovery of large amplitude X-ray variability in the low luminosity AGN (LLAGN) MGC 7589, and present possible observational evidence for accretion mode transition i…
Periodic mode changing in PSR J1048-5832
W. M. Yan, R. N. Manchester, N. Wang +4
By analysing the data acquired from the Parkes 64-m radio telescope at 1369 MHz, we report on the phase-stationary non-drift amplitude modulation observed in PSR J1048-5832. The hi…
Probing the emission states of PSR J1107-5907
Jingbo Wang, George Hobbs, Matthew Kerr +14
The emission from PSR J1107-5907 is erratic. Sometimes the radio pulse is undetectable, at other times the pulsed emission is weak, and for short durations the emission can be very…
Discovery of a soft X-ray lag in the Ultraluminous X-ray Source NGC 1313 X-1
E. Kara, C. Pinto, D. J. Walton +14
Ultraluminous X-ray Sources (ULXs) provide a unique opportunities to probe the geometry and energetics of super-Eddington accretion. The radiative processes involved in super-Eddin…
Distance and Evolutionary States of Supernova Remnant G18.9-1.1 and Candidate G28.6+0.0
S. Ranasinghe, D. Leahy, W. W. Tian
HI spectra of the supernova remnant G18.9-1.1 and the supernova remnant candidate G28.6+0.0 are analyzed. We compared the spectra to CO emission spectra and to spectra of HI…
GRB 190114C in the nuclear region of an interacting galaxy -- A detailed host analysis using ALMA, HST and VLT
A. de Ugarte Postigo, C. C. Thöne, S. Martın +28
GRB 190114C is the first GRB for which the detection of very-high energy emission up to the TeV range has been reported. It is still unclear whether environmental properties might…
Evolution implications of neutron star magnetic fields: inferred from pulsars and cyclotron lines of HMXBs
Chang-Qing Ye, De-Hua Wang, Cheng-Min Zhang +1
The evolution of neutron star (NS) magnetic field (B-field) has long been an important topic, which is still not yet settled down. Here, we analyze the NS B-fields inferred by the…
The spatial distribution of circumstellar material of the wind-fed system GX 301-2
Xueying Zheng, Jiren Liu, Lijun Gou
The distribution of the circumstellar material in systems of supergiant X-ray binaries (SgXBs) is complex and not well probed observationally. We report a detailed study of the spa…
The first six months of the Advanced LIGO's and Advanced Virgo's third observing run with GRANDMA
S. Antier, S. Agayeva, V. Aivazyan +74
We present the Global Rapid Advanced Network Devoted to the Multi-messenger Addicts (GRANDMA). The network consists of 21 telescopes with both photometric and spectroscopic facilit…
The Formation of a 70 Msun Black Hole at High Metallicity
K. Belczynski, R. Hirschi, E. A. Kaiser +7
A 70Msun BH was discovered in Milky Way disk in a long period and almost circular detached binary system (LB-1) with a high metallicity 8Msun B star companion. Current consensus on…
GRB171010A / SN2017htp: a GRB-SN at z=0.33
A. Melandri, D. B. Malesani, L. Izzo +41
The number of supernovae known to be connected with long-duration gamma-ray bursts is increasing and the link between these events is no longer exclusively found at low redshift ($…
