Discovery of 51 pulsars in a reanalysis of the Green Bank North Celestial Cap Survey and a revised pulsar census
R. Sengar, L. Vleeschower, D. L. Kaplan +13
We present results from a reanalysis of the Green Bank North Celestial Cap (GBNCC) survey, conducted at 350 MHz with the Green Bank Telescope between 2009 and 2020, covering the sk…
Radio and Gamma-Ray Timing of a Newly Discovered Millisecond Pulsar
L. Vleeschower, R. Sengar, L. Nieder +17
We report the discovery and timing of PSR J2147-3604, a fully recycled millisecond pulsar with a spin period of 3.2 ms, discovered in a reprocessing of the 350-MHz Green Bank North…
Fifteen new millisecond pulsars in 47 Tucanae
W. Chen, D. Risbud, P. C. C. Freire +16
47 Tucanae is one of the largest, brightest, and closest globular clusters to Earth. It hosts an exotic stellar population with stellar dynamics that indicate a complex evolution h…
The GMRT High-Resolution Southern Sky Survey for pulsars and transients -- VIII: Orbital Variability and the Evolution of a 1-Day He-WD Millisecond Pulsar J2101-4802
Ankita Ghosh, Bhaswati Bhattacharyya, David L. Kaplan +8
We present timing and orbital phase-resolved polarimetry of the millisecond pulsar (MSP) J21014802, having a spin period of 9.48~ms and dispersion measure (DM) $25.05\ \mathrm{p…
Pulsar Discoveries from the TRAPUM UHF Survey of Fermi-LAT Sources
Tinn Thongmeearkom, Colin J. Clark, Rene P. Breton +25
The Fermi Large Area Telescope (LAT) provides advantages for radio pulsar searches by enabling efficient target selection. We can confidently point radio telescopes to the position…
Long-term timing of the relativistic binary PSR J1906+0746
L. Vleeschower, B. W. Stappers, M. J. Keith +9
We conducted a timing analysis of over 18 years of data on the young ( kyr, \,ms) relativistic binary PSR~J1906+0746, using six radio telescopes: Arecibo,…
Discoveries and Timing of Pulsars in M62
L. Vleeschower, A. Corongiu, B. W. Stappers +14
Using MeerKAT, we have discovered three new millisecond pulsars (MSPs) in the bulge globular cluster M62: M62H, M62I, and M62J. All three are in binary systems, which means all ten…
A targeted radio pulsar survey of redback candidates with MeerKAT
T. Thongmeearkom, C. J. Clark, R. P. Breton +18
Redbacks are millisecond pulsar binaries with low mass, irradiated companions. These systems have a rich phenomenology that can be used to probe binary evolution models, pulsar win…
Discovery and timing of ten new millisecond pulsars in the globular cluster Terzan 5
P. V. Padmanabh, S. M. Ransom, P. C. C. Freire +23
We report the discovery of ten new pulsars in the globular cluster Terzan 5 as part of the Transients and Pulsars with MeerKAT (TRAPUM) Large Survey Project. We observed Terzan 5 a…
MeerKAT discovery of 13 new pulsars in Omega Centauri
W. Chen, P. C. C. Freire, A. Ridolfi +21
The most massive globular cluster in our Galaxy, Omega Centauri, is an interesting target for pulsar searches, because of its multiple stellar populations and the intriguing possib…
The TRAPUM L-band survey for pulsars in Fermi-LAT gamma-ray sources
C. J. Clark, R. P. Breton, E. D. Barr +35
More than 100 millisecond pulsars (MSPs) have been discovered in radio observations of gamma-ray sources detected by the Fermi Large Area Telescope (LAT), but hundreds of pulsar-li…
A MeerKAT look at the polarization of 47 Tucanae pulsars: magnetic field implications
F. Abbate, A. Possenti, A. Ridolfi +17
We present the polarization profiles of 22 pulsars in the globular cluster 47 Tucanae using observations from the MeerKAT radio telescope at UHF-band (544-1088 MHz) and report prec…
Discoveries and Timing of Pulsars in NGC 6440
L. Vleeschower, B. W. Stappers, M. Bailes +19
Using the MeerKAT radio telescope, a series of observations have been conducted to time the known pulsars and search for new pulsars in the globular cluster NGC 6440. As a result,…
