Three New Long Period X-ray Pulsars Discovered in the Small Magellanic Cloud [PDF]

, 2003
The Small Magellanic Cloud is increasingly an invaluable laboratory for studying accreting and isolated X-ray pulsars. We add to the class of compact SMC objects by reporting the discovery of three new long period X-ray pulsars detected with the {\it ...

Testing Lorentz violation with binary pulsars: constraints on standard model extension [PDF]

, 2012
Under the standard model extension (SME) framework, Lorentz invariance is tested in five binary pulsars: PSR J0737−3039, PSR B1534+12, PSR J1756−2251, PSR B1913+16 and PSR B2127+11C.

Recent Developments in Degenerate Higher Order Scalar Tensor Theories

Annalen der Physik, Volume 537, Issue 2, February 2025.
Degenerate Higher Order Scalar Tensor theories are reviewed, together with their applications in cosmology and astrophysics. These theories have been applied to build models of the early universe, in the description of the late‐time cosmic acceleration, as well as in astrophysics, including black hole physics. They have the potential to provide answers

A Relativistic Double Neutron Star Binary PSR J1846-0513

The Astrophysical Journal Letters
We report the timing analysis of PSR J1846−0513, a pulsar discovered by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in Commensal Radio Astronomy FAST Survey. The pulsar possesses a spin period of 23.36 ms and a spin-down rate ( $\dot{

Eight new MSPs in NGC 6440 and NGC 6441

, 2007
We report the discovery of five new millisecond pulsars in the globular cluster NGC 6440 and three new ones in NGC 6441; each cluster has one previously known pulsar. Four of the new pulsars are found in binary systems.

Formation of Short-Period Binary Pulsars in Globular Clusters [PDF]

, 1999
We present a new dynamical scenario for the formation of short-period binary millisecond pulsars in globular clusters. Our work is motivated by the recent observations of 20 radio pulsars in 47 Tuc.

Binary pulsars studies with multiwavelength sky surveys - I. Companion star identification

, 2014
The identification of the stellar companions to binary pulsars is key to studying the evolution of the binary system and how this is influenced by the interactions between the two stars.

An Algebraic Approach to Light–Matter Interactions

Advanced Physics Research, Volume 4, Issue 1, January 2025.
This is a review of an algebraic approach to light–matter interactions that is theoretically powerful and computationally friendly. Theoretical expressions can be developed and manipulated conveniently thanks to the generality of the basis on which the approach rests, and a compact notation.

XMM‐Newton Observations of the Peculiar Be X‐Ray Binary A0538‐66

Astronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT A0538‐66 is a neutron star/Be x‐ray binary located in the Large Magellanic Cloud and, since its discovery in the 70s, it showed a peculiar behavior that makes it a unique object in the high‐mass x‐ray binaries scene: the extremely eccentric orbit (e=0.72$$ e=0.72 $$), the short spin period of the neutron star (P=69$$ P=69 $$ ms), the episodes ...
