Discovery of two new millisecond pulsars towards the Galactic bulge
J. Berteaud, F. Calore, M. Clavel +13
The mysterious Galactic Center Excess of gamma rays could be explained by a large population of millisecond pulsars hiding in the Galactic bulge, too faint to be detected as indivi…
Combining the second data release of the European Pulsar Timing Array with low-frequency pulsar data
F. Iraci, A. Chalumeau, C. Tiburzi +46
Low-frequency radio data improve the sensitivity of pulsar timing arrays (PTAs) to propagation effects such as dispersion measure (DM) variations, enabling better noise characteriz…
Observing radio transients with Phased ALMA: Pulses from the Galactic Centre magnetar
J. Vera-Casanova, M. Cruces, K. Liu +7
Radio transients, such as pulsars and Fast Radio Bursts (FRBs), are primarily detected at centimetre radio wavelengths, where higher luminosities are found. However, observations o…
A survey for radio pulsars and transients in the 10 pc region around Sgr A*
G. Desvignes, R. P. Eatough, Y. Men +7
Here we report on a new survey for pulsars and transients in the 10 pc region around Sgr A* using the Effelsberg radio telescope at frequencies between 4 to 8 GHz. Our calibrated f…
The impact on astrometry by solar-wind effect in pulsar timing
K. Liu, A. Parthasarathy, M. Keith +16
Astrometry of pulsars, particularly their distances, serves as a critical input for various astrophysical experiments using pulsars. Pulsar timing is a primary approach for determi…
Broadband Multi-wavelength Properties of M87 during the 2018 EHT Campaign including a Very High Energy Flaring Episode
J. C. Algaba, M. Balokovic, S. Chandra +738
The nearby elliptical galaxy M87 contains one of the only two supermassive black holes whose emission surrounding the event horizon has been imaged by the Event Horizon Telescope (…
