A survey for millisecond pulsars [PDF]

open access: yes, 1996
We have searched 960 square degrees of sky for radio pulsars, using the 305 m telescope at Arecibo, Puerto Rico. The 430 MHz survey reached a limiting sensitivity for slow pulsars of 0.7 mJy using a dual-polarization, 32 channel filter bank over 8 MHz of

Defining Millisecond Pulsars [PDF]

open access: yes, 2023
Millisecond pulsars (MSP) are an important subclass of rotation powered pulsars (RPP), traditionally defined as those with $P_s < 20-30$~ms and $B_s \lesssim 10^{10}$~G.

Spin frequency distributions of binary millisecond pulsars [PDF]

open access: yes, 2014
Rotation-powered millisecond radio pulsars have been spun up to their present spin period by a 108−109 yr long X-ray-bright phase of accretion of matter and angular momentum in a low-to-intermediate mass binary system.

Exploring Precision Timing of Millisecond Pulsars with Wide-Bandwidth Observations

open access: yes, 2023
This thesis studies the masses, velocities, and interstellar medium effects of rapidly spinning neutron stars called millisecond pulsars. The masses of seven pulsars and their binary companions are measured.

The GMRT High Resolution Southern Sky Survey for Pulsars and Transients. V. Localization of Two Millisecond Pulsars

open access: yesThe Astrophysical Journal, 2023
The timing follow-up of newly discovered millisecond pulsars (MSPs) is hindered by the larger positional uncertainty (a few tens of arcminutes) associated with the discovery.

Scintillation Velocities of Five Millisecond Pulsars

open access: yes, 2000
Millisecond pulsars differ from normal pulsars in their mode of origin and their properties. They are thought to be born either through binary interaction or through accretion-induced collapse (AIC) of white dwarf stars.

Aharonov–Bohm Effect for Cooper Pairs in Kerr Spacetime: Gravitomagnetic Phase Shifts From Frame Dragging

open access: yesAnnalen der Physik, Volume 538, Issue 8, August 2026.
ABSTRACT The unification of quantum mechanics and general relativity remains a central problem in fundamental physics. Here, we study the gravitomagnetic Aharonov–Bohm (AB) effect for Cooper pairs in Kerr spacetime. Frame‐dragging by a rotating black hole (BH) generates an effective vector potential through the off‐diagonal metric term gtϕ$g_{t\phi }$,

Gravitational Radiation From Binary Systems With Time Varying Masses

open access: yesAnnalen der Physik, Volume 538, Issue 8, August 2026.
We extend the standard approach pioneered in the works by Peters and Mathews to include the mass loss processes of the binary components, by obtaining the variations due to gravitational radiation of the main physical parameters. As an application of our results we consider gravitational radiation emission in binary magnetar systems.

Mitochondria Dictate Progressive Versus Bimodal Aging of the Mammary Gland

open access: yesAging Cell, Volume 25, Issue 8, August 2026.
Breast cancer shows a bimodal age distribution with a peak at 45 and higher peak at 65. Using mice with different mitochondrial genomes, we show progressive and bimodal patterns of aging of the mammary gland with distinct pro‐tumorigenic age windows. This finding may shed light on the bimodal distribution in humans.

A Perspective of Multi‐Reflecting TOF MS

open access: yesMass Spectrometry Reviews, Volume 45, Issue 3, Page 476-506, May/June 2026.
ABSTRACT Time‐of‐flight mass spectrometry (TOF MS) excels in rapid and high‐sensitivity analysis, making it a cornerstone of analytical chemistry. But as sample complexity explodes in omics studies, so does the need for higher resolving power to ensure accurate results.
