Low-frequency wideband timing of InPTA pulsars observed with the uGMRT
K Nobleson, Nikita Agarwal, Raghav Girgaonkar +29
High-precision measurements of the pulsar dispersion measure (DM) are possible using telescopes with low-frequency wideband receivers. We present an initial study of the applicatio…
Recent formation and likely cometary activity of near-Earth asteroid pair 2019 PR2 -- 2019 QR6
Petr Fatka, Nicholas A. Moskovitz, Petr Pravec +13
Asteroid pairs are genetically related asteroids that recently separated (few million years), but still reside on similar heliocentric orbits. A few hundred of these systems hav…
Noise analysis in the European Pulsar Timing Array data release 2 and its implications on the gravitational-wave background search
A. Chalumeau, S. Babak, A. Petiteau +49
The European Pulsar Timing Array (EPTA) collaboration has recently released an extended data set for six pulsars (DR2) and reported evidence for a common red noise signal. Here we…
Polarimetric Properties of the Near--Sun Asteroid (155140) 2005 UD in Comparison with Other Asteroids and Meteoritic Samples
Masateru Ishiguro, Yoonsoo P. Bach, Jooyeon Geem +26
The investigation of asteroids near the Sun is important for understanding the final evolutionary stage of primitive solar system objects. A near-Sun asteroid, (155140) 2005 UD, ha…
Search for fast radio transients using Arecibo drift-scan observations at 1.4 GHz
B. B. P. Perera, A. J. Smith, S. Vaddi +12
We conducted a drift-scan observation campaign using the 305-m Arecibo telescope in January and March 2020 when the observatory was temporarily closed during the intense earthquake…
Common-red-signal analysis with 24-yr high-precision timing of the European Pulsar Timing Array: Inferences in the stochastic gravitational-wave background search
S. Chen, R. N. Caballero, Y. J. Guo +49
We present results from the search for a stochastic gravitational-wave background (GWB) as predicted by the theory of General Relativity using six radio millisecond pulsars from th…
Asteroid 16 Psyche: Shape, Features, and Global Map
Michael K. Shepard, Katherine de Kleer, Saverio Cambioni +9
We develop a shape model of asteroid 16 Psyche using observations acquired in a wide range of wavelengths: Arecibo S-band delay-Doppler imaging, Atacama Large Millimeter Array (ALM…
Evidence for profile changes in PSR J1713+0747 using the uGMRT
Jaikhomba Singha, Mayuresh P Surnis, Bhal Chandra Joshi +29
PSR J1713+0747 is one of the most precisely timed pulsars in the international pulsar timing array experiment. This pulsar showed an abrupt profile shape change between April 16, 2…
Habitability Models for Astrobiology
Abel Méndez, Edgard E. Rivera-Valentín, Dirk Schulze-Makuch +31
Habitability has been generally defined as the capability of an environment to support life. Ecologists have been using Habitat Suitability Models (HSMs) for more than four decades…
Study of 72 pulsars discovered in the PALFA survey: Timing analysis, glitch activity, emission variability, and a pulsar in an eccentric binary
E. Parent, H. Sewalls, P. C. C. Freire +31
We present new discoveries and results from long-term timing of 72 pulsars discovered in the Arecibo PALFA survey, including precise determination of astrometric and spin parameter…
Multi-frequency study of the peculiar pulsars PSR B0919+06 and PSR B1859+07
K. M. Rajwade, B. B. P. Perera, B. W. Stappers +3
Since their discovery more than 50 years ago, broadband radio studies of pulsars have generated a wealth of information about the underlying physics of radio emission. In order to…
Radio Detection of PSR J1813-1749 in HESS J1813-178: The Most Scattered Pulsar Known
F. Camilo, S. M. Ransom, J. P. Halpern +1
The 44.7 ms X-ray pulsar in the supernova remnant G12.82-0.02/HESS J1813-178 has the second highest spin-down luminosity of known pulsars in the Galaxy, with E-dot=5.6e37 erg/s. Us…
A Transient Coronal Sigmoid in Active Region NOAA 11909: Build-up Phase, M-class Eruptive Flare, and Associated Fast Coronal Mass Ejection
Hema Kharayat, Bhuwan Joshi, Prabir K. Mitra +2
In this article, we investigate the formation and disruption of a coronal sigmoid from the active region (AR) NOAA 11909 on 07 December 2013, by analyzing multi-wavelength and mult…
