Radio emission from beyond the light cylinder in millisecond pulsars
Michael Kramer, Simon Johnston
A striking aspect of the radio profiles of many millisecond pulsars (MSPs) is that they consist of components separated from each other by regions lacking in emission. We devise a…
Unveiling frequency-dependent eclipsing in spider millisecond pulsars using broadband polarization observations with the Parkes
Sangita Kumari, Bhaswati Bhattacharyya, Rahul Sharan +6
This study presents an orbital phase-dependent analysis of three black widow spider millisecond pulsars (BW MSPs), aiming to investigate the magnetic field within the eclipse envir…
Multiwavelength pulsations and surface temperature distribution in the middle-aged pulsar B1055-52
Armin Vahdat, Bettina Posselt, George G. Pavlov +3
We present a detailed study of the X-ray emission from PSR B1055-52 using XMM-Newton observations from 2019 and 2000. The phase-integrated X-ray emission from this pulsar is poorly…
Linear to circular conversion in the polarized radio emission of a magnetar
Marcus E. Lower, Simon Johnston, Maxim Lyutikov +13
Radio emission from magnetars provides a unique probe of the relativistic, magnetized plasma within the near-field environment of these ultra-magnetic neutron stars. The transmitte…
The Polarized Cosmic Hand: IXPE Observations of PSR B1509-58/MSH 15-52
Roger W. Romani, Josephine Wong, Niccolo Di Lalla +99
We describe IXPE polarization observations of the Pulsar Wind Nebula (PWN) MSH15-52, the `Cosmic Hand'. We find X-ray polarization across the PWN, with B field vectors generally al…
The Thousand-Pulsar-Array programme on MeerKAT XI: Application of the rotating vector model
Simon Johnston, Michael Kramer, Aris Karastergiou +4
In spite of the rich phenomenology of the polarization properties of radio pulsars, the rotating vector model (RVM) created 50 years ago remains the best method to determine the be…
