Spectral Studies of Super‐Eddington Accreting Neutron Stars in the Magellanic Clouds

Astronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT Major outbursts of BeXRBs offer a unique laboratory for studying accretion onto magnetized neutron stars (NSs) over a large dynamic range. The accreting material is entrained from the accretion disk by the strong magnetic field, and then channeled onto the NS, forming a so‐called accretion column (AC).

Change of Rotation Measure during the Eclipse of a Black Widow PSR J2051−0827

The Astrophysical Journal, 2023
Black widows are millisecond pulsars ablating their companions. The material blown from the companion blocks the radio emission, resulting in radio eclipses. The properties of the eclipse medium are poorly understood.

Characterization of fatty acid forms using benchtop NMR in omega‐3 oil supplements

Magnetic Resonance in Chemistry, Volume 62, Issue 5, Page 328-336, May 2024.
The proposed method uses benchtop NMR equipment as a tool for the quality control of commercial oil supplements. NMR experiments 1D 1H and 2D 1H‐1H COSY provide a quick and accurate approach to screen the forms of omega‐3 fatty acids in oils: triacylglycerols (TAGs), ethyl esters (EEs), and diacylglycerol (DAGs) and evaluate their ratio. Abstract Omega‐

The Third Fermi Large Area Telescope Catalog of Gamma-Ray Pulsars

The Astrophysical Journal, 2023
We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio searches of LAT sources will likely reveal pulsations once phase-connected

Search for Short‐Duration Transient Gravitational Waves Emitted by Neutron Star Glitches

Annalen der Physik, Volume 536, Issue 2, February 2024.
The observation rate of pulsar glitches is limited by their electromagnetic observations. There could be a population of the isolated neutron stars in the galaxy for which there is no electromagnetic observations, but they can produce gravitational waves. The all‐sky search for gravitational waves provides better localization of the source sky position
