Using the Markov Chain Monte Carlo method to study the physical properties GeV-TeV BL Lac objects
Longhua Qin, Jiancheng Wang, Chuyuan Yang +3
We fit the spectral energy distributions (SEDs) of 46 GeV - TeV BL Lac objects in the frame of leptonic one-zone synchrotron self-Compton (SSC) model and investigate the physical p…

In order to search for the evidence of quasi-periodic oscillation (QPO) in blazar, multicolor optical observations of the BL Lacertae object S5 0716+714 were performed from 2005 to…
Energetic eruptions leading to a peculiar hydrogen-rich explosion of a massive star
Iair Arcavi, D. Andrew Howell, Daniel Kasen +50
Every supernova hitherto observed has been considered to be the terminal explosion of a star. Moreover, all supernovae with absorption lines in their spectra show those lines decre…
A Method for Locating High Energy Dissipation Region in Blazar

The production site of gamma-rays in blazar jet is an unresolved problem. We present a method to locate gamma-ray emission region in the framework of one-zone emission model. From…
Constraints on the location of -ray emitting region for a sample of blazars with radio core-shift measurements
Linhui Wu, Qingwen Wu, Dahai Yan +2
We model simultaneous or quasi-simultaneous multi-band spectral energy distributions (SEDs) for a sample of 25 blazars that have radio core-shift measurements, where a one-zone lep…
Millisecond pulsar origin of the Galactic center excess and extended gamma-ray emission from Andromeda - a closer look

We report on SALT low resolution optical spectroscopy and optical/IR photometry undertaken with other SAAO telescopes (MASTER-SAAO and IRSF) of the kilonova AT 2017gfo (aka SSS17a)…
The Rapid Reddening and Featureless Optical Spectra of the optical counterpart of GW170817, AT 2017gfo, During the First Four Days
Curtis McCully, Daichi Hiramatsu, D. Andrew Howell +17
We present the spectroscopic evolution of AT 2017gfo, the optical counterpart of the first binary neutron star (BNS) merger detected by LIGO and Virgo, GW170817. While models have…
The unpolarized macronova associated with the gravitational wave event GW170817
S. Covino, K. Wiersema, Y. Z. Fan +37
The merger of two dense stellar remnants including at least one neutron star (NS) is predicted to produce gravitational waves (GWs) and short duration gamma ray bursts (GRBs). In t…
Follow up of GW170817 and its electromagnetic counterpart by Australian-led observing programs
I. Andreoni, K. Ackley, J. Cooke +122
The discovery of the first electromagnetic counterpart to a gravitational wave signal has generated follow-up observations by over 50 facilities world-wide, ushering in the new era…
Constraining the redshifts of TeV BL Lac objects
Longhua Qin, Jiancheng Wang, Dahai Yan +3
We present a model-dependent method to estimate the redshifts of three TeV BL Lac objects (BL Lacs) through fltting their (quasi-) simultaneous multi-waveband spectral energy distr…
SN 2016coi/ASASSN-16fp: An example of residual helium in a type Ic supernova?
S. J. Prentice, C. Ashall, P. A. Mazzali +35
The optical observations of Ic-4 supernova (SN) 2016coi/ASASSN-16fp, from to days after explosion, are presented along with analysis of its physical properties.…
A mixture evolution scenario of the AGN radio luminosity function. II. Do low- and high-power radio-loud AGNs evolve differently?
Zunli Yuan, Jiancheng Wang, Ming Zhou +2
Following previous work, we further confirm that the cosmic evolution of steep-spectrum radio-loud AGNs (active galactic nuclei) can be reproduced by a simple combination of densit…
A tale of two transients: GW170104 and GRB170105A
