Population of X-ray Sources in the Intermediate-Age Cluster NGC 3532: a Test Bed for Machine-Learning Classification

Steven Chen, Oleg Kargaltsev, Hui Yang +4

Open clusters are thought to be the birth place of most stars in the Galaxy. Thus, they are excellent laboratories for investigating stellar evolution, and X-ray properties of vari…

A NuSTAR and Chandra Investigation of the Misaligned Outflow of PSR J1101-6101 and the Lighthouse Pulsar Wind Nebula

Noel Klingler, Jeremy Hare, Oleg Kargaltsev +2

PSR J1101-6101 is an energetic young pulsar which powers the remarkable Lighthouse pulsar wind nebula (PWN). The pulsar belongs to the rare type of radio- and gamma-ray-quiet pulsa…

Temporal and Spectral Evolution of Gamma-ray Burst Broad Pulses: Identification of High Latitude Emission in the Prompt Emission

Donggeun Tak, Z. Lucas Uhm, Judith Racusin +5

We perform a detailed analysis on broad pulses in bright Gamma-ray bursts (GRBs) to understand the evolution of GRB broad pulses. Using the temporal and spectral properties, we tes…

XMM-Newton and Chandra observations of the candidate Fermi-LAT pulsar 4FGL J1015.5-6030

Jeremy Hare, Oleg Kargaltsev, George Younes +2

4FGL J1015.5-6030 is an unidentified Fermi-LAT source hosting a bright, extended X-ray source whose X-ray spectrum is consistent with that of a young pulsar, yet no pulsations have…

A Cosmological Fireball with Sixteen-Percent Gamma-Ray Radiative Efficiency

Liang Li, Yu Wang, Felix Ryde +9

Gamma-ray bursts (GRBs) are the most powerful explosions in the universe. How efficiently the jet converts its energy to radiation is a long-standing problem and it is poorly const…

The radio structure of the -ray narrow-line Seyfert 1 galaxy SDSS J211852.96073227.5

Xi Shao, Minfeng Gu, Yongjun Chen +4

The -ray narrow-line Seyfert 1 (NLS1) galaxies can be considered to be the third class of -ray active galactic nuclei possessing relativistic jets. In this paper, we present…
