Unveiling Low-frequency Eclipses in Spider Millisecond Pulsars Using Wideband GMRT Observations
The Astrophysical JournalEclipses of radio emission have been reported for ∼58 spider millisecond pulsars (MSPs), of which only around 19% have been extensively studied. Such studies at low frequencies are crucial for probing the properties of the eclipse medium.

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.

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

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 ...

The Role of XMM–Newton in the Investigation of Persistent BeXRBs
Astronomische Nachrichten, Volume 346, Issue 1, January 2025.ABSTRACT The persistent BeXRBs are a class of high‐mass X‐ray binaries (HMXRBs), which are characterized by persistent low X‐ray luminosities (LX~1034$$ {L}_{\mathrm{X}}\sim {10}^{34} $$ erg s −1$$ {}^{-1} $$) and wide (Porb>$$ {P}_{\mathrm{orb}}> $$ 30 days), almost circular orbits. In these sources the NS is slowly rotating (with Pspin$$ {P}_{\mathrm{

Beyond Accretion Limits: The Rise of Pulsating Gems
Astronomische Nachrichten, Volume 346, Issue 1, January 2025.ABSTRACT The discovery of several ultraluminous X‐ray sources exhibiting fast and rapidly evolving X‐ray pulsations unequivocally associates these sources with accreting neutron stars orbiting relatively massive companion stars (> 8M ⊙$$ {}_{\odot } $$).
