IXPE Observations of the Blazar Mrk 501 in 2022: A Multiwavelength View

L. Lisalda, E. Gau, H. Krawczynski +157

The blazar Markarian 501 (Mrk 501) was observed on three occasions over a 4-month period between 2022 March and 2022 July with the Imaging X-ray Polarimetry Explorer (IXPE). In thi…

X-ray polarimetry of X-ray pulsar X Persei: another orthogonal rotator?

A. A. Mushtukov, S. S. Tsygankov, J. Poutanen +103

X Persei is a persistent low-luminosity X-ray pulsar of period of 835 s in a Be binary system. The field strength at the neutron star surface is not known precisely, but indi…

Recoil imaging for directional detection of dark matter, neutrinos, and physics beyond the Standard Model

C. A. J. O'Hare, D. Loomba, K. Altenmüller +164

Recoil imaging entails the detection of spatially resolved ionization tracks generated by particle interactions. This is a highly sought-after capability in many classes of detecto…
