Characterizing Timing Noise in Normal Pulsars with the Nanshan Radio Telescope
UniverseWe present a decade of observations of pulse arrival times for 85 pulsars using the Nanshan radio telescope from July 2002 to March 2014. The Cholesky method can accurately estimate the covariance function of the timing residuals, significantly improving

Relativistic Effects of Rotation in γ-ray Pulsars—Invited Review
Galaxies, 2021 In this paper, we consider the relativistic effects of rotation in the magnetospheres of γ-ray pulsars. The paper reviews the progress achieved in this field during the last three decades.

ARECIBO PULSAR SURVEY USING ALFA. IV. MOCK SPECTROMETER DATA ANALYSIS, SURVEY SENSITIVITY, AND THE DISCOVERY OF 40 PULSARS [PDF]
, 2015 The on-going Arecibo Pulsar-ALFA (PALFA) survey began in 2004 and is searching for radio pulsars in the Galactic plane at 1.4 GHz. Here we present a comprehensive description of one of its main data reduction pipelines that is based on the PRESTO ...

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range
Wildlife Society Bulletin, EarlyView.We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

Three-dimensional analytical description of magnetized winds from oblique pulsars [PDF]
, 2015 Rotating neutron stars, or pulsars, are plausibly the source of power behind many astrophysical systems, such as gamma-ray bursts, supernovae, pulsar wind nebulae and supernova remnants.

Translational Remodeling of the Synaptic Proteome During Aging
Aging Cell, EarlyView.Aging induces a decoupling of protein regulation between the soma and the synapse. In particular, transcripts coding for ribosomal proteins decrease and their corresponding proteins increase in the synapse while the opposite happens in the soma. At the same time, synapse‐specific regulation of splicing takes place.

Understanding the diffuse gamma ray emission of the milky way - from supernova remnants to dark matter [PDF]
Zbornik Matice Srpske za Prirodne Nauke, 2019 Diffuse gamma ray emission from the Galactic center at 2-3 GeV, as well as the 12 TeV gamma ray excess in the Galactic disk, remain open for debate and represent the missing puzzles in the complete picture of the high-energy Milky Way sky.

Testing Relativistic Gravity with Radio Pulsars [PDF]
, 2014 Before the 1970s, precision tests for gravity theories were constrained to the weak gravitational fields of the Solar system. Hence, only the weak-field slow-motion aspects of relativistic celestial mechanics could be investigated. Testing gravity beyond

Detecting dark matter with imploding pulsars in the galactic center. [PDF]
Physical Review Letters, 2014 The paucity of old millisecond pulsars observed at the galactic center of the Milky Way could be the result of dark matter accumulating in and destroying neutron stars.
