IXPE Observations of the Quintessential Wind-accreting X-Ray Pulsar Vela X-1

The radiation from accreting X-ray pulsars was expected to be highly polarized, with some estimates for the polarization degree of up to 80%. However, phase-resolved and energy-resolved polarimetry of X-ray pulsars is required in or...

Origin of the spectacular tidal shells of galaxy NGC 474

The lenticular galaxy NGC 474 hosts a rich system of tidal shells and streams, some of which are exceptionally bright. Two teams recently presented spectroscopic observations of the brightest shells. These were the first shell spectra ever observed i...

Images of stars and sparks in May: anthropological and ontological testimonies

The article explores the role played by the motif of stars and sparks in the first to third songs of Macha’s poem May. Stars appear in the first canto, both in reference to stars whose light is going out and in the form of sparks (the reflection of <...
