We present here the first convincing observational manifestation of a magnetar-like magnetic field in an accreting neutron star in binary system - the first pulsating ultra-luminous X-ray source X-2 in the galaxy M82. Using the Chandra X-ray observatory data we show that the source exhibit the bimodal distribution of the luminosity with two well-defined peaks separated by a factor of 40. This behaviour can be interpreted as the action of the "propeller regime" of accretion. The onset of the propeller in a 1.37 s pulsar at luminosity of ~$10^{40}$ erg/s implies the dipole component of the neutron star magnetic field of ~$10^{14}$ G.

  1. Significant or Not? The Impact of Randomisation During Data Reduction on Confirming a New Pulsating Ultraluminous X-ray Source Candidate in Centaurus A

    astro-ph.HE 2026-05 conditional novelty 7.0

    A soft-spectrum PULX candidate is reported in Cen A but XMM-SAS randomisation during data reduction renders the marginal 1.27 Hz pulsation detection unreliable across repeated reductions.

  2. Deep optical spectroscopic monitoring of the pulsating ULX NGC 1313 X-2 with longslit Gemini observations

    astro-ph.HE 2026-06 unverdicted novelty 4.0

    Gemini spectroscopy suggests an A-type supergiant donor in NGC 1313 X-2 and provides updated constraints on orbital parameters, disk size, and gas bubble expansion.
