Tootfinder

letzten donnerstag wollte ich nur kurz eine bestellung für ein buchgeschenk für jemanden in der familie in der münsteraner "schatzinsel" abholen. da ich ein paar minuten zeit zum stöbern hatte, konnte ich mir dann die beiden neusten eichhörnchen-bücher von olivier tallec schenken. 😊
"mein bester bester freund" und "ist amsel tot?" – wieder mal große themen, und wieder sehr schön umgesetzt.

Probing the emission geometry of the X-ray pulsar 2S 1417$-$624 during a weak outburst with NICER, IXPE, and NuSTAR
We report results from a multi-mission observational campaign of the transient X-ray pulsar 2S~1417$-$624 during its 2025 outburst, using data from NICER, IXPE, and NuSTAR. Phase-averaged and phase-resolved spectroscopy with NICER and NuSTAR reveal that a typical power-law model with a high-energy cut-off well describes the broadband spectra. Several spectral parameters, however, show clear and systematic modulations with pulse phase, indicating variations in the physical conditions of the emit…

Unraveling the structure of the stratified ultra-fast outflows in PDS 456 with XRISM
Multiple clumpy wind components ($v_{out}\sim0.2-0.3c$) in the luminous quasar PDS 456 have recently been resolved by XRISM in the Fe-K band for the first time. In this paper, we investigate the structure of ultra-fast outflows (UFOs) using coordinated observations from XRISM, XMM-Newton, and NuSTAR, along with the self-consistently calculated photoionization model \texttt{PION}. Our results reveal a stratified ionization structure likely driven by the radiation field, characterized by a relati…
