Is Fermi 1544-0649 a misaligned blazar? discovering the jet structure with VLBI
Chengyu Shao, Xiaopeng Cheng, Tam Pak-Hin Thomas +8
Fermi J1544-0649 is a transient GeV source first detected during its GeV flares in 2017. Multi-wavelength observations during the flaring time demonstrate variability and spectral…
Searching for an additional high-energy component in Fermi-LAT GRB afterglows
Xin-Bo He, Pak-Hin Thomas Tam, Guang-Bo Long +3
The VHE component from at least two GRBs, i.e., GRB180720B and GRB190114C, has been detected in the afterglow phase. We systematically analyzed 199 GRBs detected by Fermi-LAT durin…
Periodicity search for Pulsar Binaries with TESS
Partha Sarathi Pal, P. H. T. Tam, Weitang Liang +4
Pulsar binaries, in particular redback systems, provide good sources to study the pulsar wind flow and its interaction with the companion stars. {\it Fermi}-LAT have proposed proba…
Multi-wavelength observations of the BL Lac object Fermi J1544-0649: one year after its awakening
P. H. T. Tam, P. S. Pal, Y. D. Cui +15
We report observations of a transient source \fermi\ from radio to \grs. \fermi\ was discovered by the {\it Fermi-LAT} in May 2017. Follow-up {\it Swift-XRT} observations revealed…
Peculiar prompt emission and afterglow in H.E.S.S. detected GRB 190829A
Vikas Chand, Ankush Banerjee, Rahul Gupta +10
We present the results of a detailed investigation of the prompt and afterglow emission in the HESS detected GRB 190829A. Swift and Fermi observations of the prompt phase of this G…
X-Ray spectral evolution of PSR~J2032+4127 during the 2017 periastron passage
Partha Sarathi Pal, P. H. Thomas Tam, Yudong Cui +3
We report X-ray data analysis results obtained from Chandra, XMM-Newton, NuSTAR and Swift observations of PSR J2032+4127 taken before, during, and after the periastron on 2017 Nove…
