A Decade of Linear and Circular Polarimetry with the POLISH2 Polarimeter
The Astrophysical Journal Supplement Series, 2023 The POLISH2 optical polarimeter has been in operation at the Lick Observatory 3 m Shane telescope since 2011, and it was commissioned at the Gemini North 8 m in 2016.

Crab pulsar spectrum: a non-extensive approach [PDF]
, 2014 Non extensive statistical physics has been applied to various problems in physics including astrophysics. In this paper we explore the possibility of using non extensive approach to explain the recently observed pulsed $\gamma$-ray from Crab pulsar above 100 GeV observed by VERITAS $\gamma$-ray telescope.

Applied SciencesPulsars are neutron stars with high rotation speeds and have extraordinary long-term rotational stability. X-ray pulsar-based navigation (XNAV) is a navigation method that estimates the position and velocity of a spacecraft using the X-ray radiation from

The Crab pulsar and its red knot in the near-infrared [PDF]
Astron.Astrophys. 406 (2003) 639-644, 2003 We present near-infrared observations obtained with ISAAC on the VLT of the Crab pulsar and its environment. Photometry of the pulsar in Js, H and Ks shows the pulsar spectrum to extend fairly smoothly from the UV/optical regime. PSF subtraction of the pulsar allows us to study its immediate neighborhood in some detail.

A New Fast Silicon Photomultiplier Photometer
Acta Polytechnica, 2011 The Crab pulsar is one of the most intensively studied X-ray/optical objects, but up to now only a small number of research groups have based their photometers on SiPM technology.

A Statistical Analysis of Crab Pulsar Giant Pulse Rates
The Astrophysical JournalA small number of pulsars are known to emit giant pulses (GPs), single pulses much brighter than average. Among these is PSR J0534+2200, also known as the Crab pulsar, a young pulsar with high GP rates. Long-term monitoring of the Crab pulsar presents an

X-Ray Observation of the 2017 November Glitch in the Crab Pulsar
Astrophysical Journal, 2018 We have observed a glitch in the Crab pulsar (PSR B0531+21) in the 0.5–10 keV X-ray band with the X-Ray Pulsar Navigation-I (XPNAV-1) satellite. This glitch occurred around 2017 November 8.

Pulsed VHE emission from the Crab Pulsar in the context of magnetocentrifugal particle acceleration [PDF]
, 2016 The Crab Pulsar has been recently detected at very high energies (VHE) with its pulsed VHE emission reaching up to $1.5$ TeV. The VHE peaks appear synchronised with the peaks at GeV energies and show VHE spectra following hard power-law functions.

Resolving the Emission Regions of the Crab Pulsar’s Giant Pulses [PDF]
Astrophysical Journal, 2017 The Crab pulsar has striking radio emission properties, with the two dominant pulse components—the main pulse and the interpulse—consisting entirely of giant pulses.
