Multiwavelength Spectral Analysis and Neural Network Classification of Counterparts to 4FGL Unassociated Sources

Stephen Kerby, Amanpreet Kaur, Abraham D. Falcone +7

The Fermi-LAT unassociated sources represent some of the most enigmatic gamma-ray sources in the sky. Observations with the Swift-XRT and -UVOT telescopes have identified hundreds…

FAST discovery of an extremely radio-faint millisecond pulsar from the Fermi-LAT unassociated source 3FGL J0318.1+0252

Pei Wang, Di Li, Colin J. Clark +23

High sensitivity radio searches of unassociated -ray sources have proven to be an effective way of finding new pulsars. Using the Five-hundred-meter Aperture Spherical radio Tel…

Refined Mass and Geometric Measurements of the High-Mass PSR J0740+6620

Emmanuel Fonseca, H. Thankful Cromartie, Timothy T. Pennucci +42

We report results from continued timing observations of PSR J0740+6620, a high-mass, 2.8-ms radio pulsar in orbit with a likely ultra-cool white dwarf companion. Our data set consi…

Discovery and timing of three millisecond pulsars in radio and gamma-rays with the GMRT and Fermi-LAT

B. Bhattacharyya, J. Roy, T. J. Johnson +14

We performed deep observations to search for radio pulsations in the directions of 375 unassociated Fermi Large Area Telescope (LAT) gamma-ray sources using the Giant Metrewave Rad…

X-ray Spectra and Multiwavelength Machine Learning Classification for Likely Counterparts to Fermi 3FGL Unassociated Sources

Stephen Kerby, Amanpreet Kaur, Abraham D. Falcone +4

We conduct X-ray spectral fits on 184 likely counterparts to Fermi-LAT 3FGL unassociated sources. Characterization and classification of these sources allows for more complete popu…
