The Polarized Cosmic Hand: IXPE Observations of PSR B1509-58/MSH 15-52

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Roger W. Romani, Josephine Wong, Niccolo Di Lalla, Nicola Omodei, Fei Xie | Summary: We describe IXPE polarization observations of the Pulsar Wind Nebula (PWN) MSH15-52, the `Cosmic Hand’. We find X-ray polarization across the PWN, with B field vectors generally aligned with filamentary X-ray structures. […]

In-situ vs accreted Milky Way globular clusters: a new classification method and implications for cluster formation

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Vasily Belokurov, Andrey Kravtsov, , , | Summary: We present a new scheme for the classification of the in-situ and accreted globular clusters (GCs). The scheme uses total energy $E$ and $z$-component of the orbital angular momentum and is calibrated using [Al/Fe] abundance ratio. We demonstrate that […]

Simulating ionization feedback from young massive stars: impact of numerical resolution

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Yunwei Deng, Hui Li, Rahul Kannan, Aaron Smith, Mark Vogelsberger | Summary: Modelling galaxy formation in hydrodynamic simulations has increasingly adopted various radiative transfer methods to account for photoionization feedback from young massive stars. However, the evolution of HII regions around stars begins in dense star-forming clouds […]
