A Fourier Domain “Jerk” Search for Binary Pulsars [PDF]
Astrophysical Journal, 2018 While binary pulsar systems are fantastic laboratories for a wide array of astrophysics, they are particularly difficult to detect. The orbital motion of the pulsar changes its apparent spin frequency over the course of an observation, essentially ...

Discovery and Timing of Millisecond Pulsars in the Globular Cluster M5 with FAST and Arecibo
The Astrophysical Journal Supplement Series, 2023 We report on a comprehensive multiwavelength study of the pulsars in the globular cluster (GC) M5, including the discovery of M5G, a new compact noneclipsing “black widow” pulsar.

Radiation Dosimetry of Binary Pulsars [PDF]
The Astrophysical Journal, 1996 Companion stars exposed to high energy radiation from a primary neutron star or accreting black hole can experience significant spallation of their heavy elements, so that their atmospheres would be extremely rich in lithium, beryllium, and especially boron. In this paper we note that the detection or non-detection of these elements, and their relative

5‐Fluoro/(trifluoromethoxy)‐2‐indolinone derivatives with anti‐interleukin‐1 activity
Archiv der Pharmazie, Volume 356, Issue 12, December 2023., 2023 Novel 5‐fluoro/(trifluoromethoxy)‐2‐indolinone derivatives were designed and synthesized based on in silico and preliminary in vitro test results from lead compounds. All compounds tested displayed nontoxic IL‐1 receptor inhibitory effects at IC50 values in the range of 10 nM to 13 µM, and seven compounds showed inhibitory responses stronger than the ...

Message in a Bottle—An Update to the Golden Record: 1. Objectives and Key Content of the Message
Earth and Space Science, Volume 10, Issue 12, December 2023., 2023 Abstract In the first part of this series, we delve into the foundational aspects of “Message in a Bottle (MIAB)” (henceforth referred to as MIAB). This study builds upon the legacy of the Voyager Golden Records, launched aboard Voyager 1 and 2 in 1977, which aimed to communicate with intelligent species beyond our world. These records not only offer a

Horndeski gravity without screening in binary pulsars [PDF]
, 2018 We test the subclasses of Horndeski gravity without Vainshtein mechanism in the strong field regime of binary pulsars. We find the rate of energy losses via the gravitational radiation predicted by such theories and compare our results with observational

Evading the Vainshtein Mechanism with Anomalous Gravitational Wave Speed: Constraints on Modified Gravity from Binary Pulsars. [PDF]
Physical Review Letters, 2015 By using observations of the Hulse-Taylor pulsar, we constrain the gravitational wave (GW) speed to the level of 10(-2). We apply this result to scalar-tensor theories that generalize Galileon 4 and 5 models, which display anomalous propagation speed and

Wildlife Society Bulletin, Volume 47, Issue 2, June 2023., 2023 Thermal technology may overcome many limitations of traditional monitoring techniques for American woodcock (Scolopax minor), however, the efficacy of this sampling method for the species remains unknown. We deployed‐ and searched for heat‐emitting woodcock mounts along transects within early‐successional habitats.

Deducing the EOS of dense neutron star matter with machine learning
Astronomische Nachrichten, Volume 344, Issue 1-2, January-February 2023., 2023 Abstract The interior of a neutron star is a unique astrophysical laboratory for studying matter at extreme densities and pressures beyond what is replicable in terrestrial experiments. While there is no direct way to simulate the interior of these stars, one promising avenue to learning more about the equation of state (EOS) of such matter is through ...

Constraints on Undetected Long-period Binaries in the Known Pulsar Population
The Astrophysical Journal, 2023 Although neutron star–black hole binaries have been identified through mergers detected in gravitational waves, a pulsar–black hole binary has yet to be detected.
