Multi-Wavelength Observations Of A New Redback Millisecond Pulsar 4FGL J1910.7-5320
Ka-Yui Au, Jay Strader, Samuel J. Swihart +9
We present the study of multi-wavelength observations of an unidentified Fermi Large Area Telescope (LAT) source, 4FGL J1910.7-5320, a new candidate redback millisecond pulsar bina…
A New Flaring Black Widow Candidate and Demographics of Black Widow Millisecond Pulsars in the Galactic Field
Samuel J. Swihart, Jay Strader, Laura Chomiuk +4
We present the discovery of a new optical/X-ray source likely associated with the Fermi -ray source 4FGL J1408.6-2917. Its high-amplitude periodic optical variability, large spe…
The ASAS-SN Bright Supernova Catalog -- V. 2018-2020
K. D. Neumann, T. W. -S. Holoien, C. S. Kochanek +55
We catalog the 443 bright supernovae discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN) in along with the 519 supernovae recovered by ASAS-SN and 516 a…
1RXH J082623.6-505741: a new long-period cataclysmic variable with an evolved donor and a low mass transfer rate
Kirill V. Sokolovsky, Jay Strader, Samuel J. Swihart +13
We report the discovery of 1RXH J082623.6-505741, a 10.4 hr orbital period compact binary. Modeling extensive optical photometry and spectroscopy reveals a K-t…
UGPS J194310+183851: an Unusual Optical and X-ray Faint Cataclysmic Variable?
C. Morris, T. J. Maccarone, P. W. Lucas +7
The growing number of multi-epoch optical and infrared sky surveys are uncovering unprecedented numbers of new variable stars, of an increasing number of types. The short interval…
A Gamma-ray Pulsar Timing Array Constrains the Nanohertz Gravitational Wave Background
M. Ajello, W. B. Atwood, L. Baldini +129
After large galaxies merge, their central supermassive black holes are expected to form binary systems whose orbital motion generates a gravitational wave background (GWB) at nanoh…
Gamma-ray Eclipses and Orbital Modulation Transitions in the Candidate Redback 4FGL J1702.7-5655
R. H. D. Corbet, L. Chomiuk, J. B. Coley +8
Observations with the Fermi Large Area Telescope (LAT) of the gamma-ray source 4FGL J1702.7-5655, previously classified as a candidate millisecond pulsar, show highly-significant m…
Discovery, Timing, and Multiwavelength Observations of the Black Widow Millisecond Pulsar PSR J1555-2908
Paul S. Ray, Lars Nieder, Colin J. Clark +21
We report the discovery of PSR J1555-2908, a 1.79 ms radio and gamma-ray pulsar in a 5.6 hr binary system with a minimum companion mass of 0.052 . This fast and energetic…
4FGL J1120.0-2204: A Unique Gamma-ray Bright Neutron Star Binary with an Extremely Low Mass Proto-White Dwarf
Samuel J. Swihart, Jay Strader, Elias Aydi +5
We have discovered a new X-ray emitting compact binary that is the likely counterpart to the unassociated Fermi-LAT GeV -ray source 4FGL J1120.0-2204, the second brightest Fermi…
