Discovery of a shock-compressed magnetic field in the north-western rim of the young supernova remnant RX J1713.7-3946 with X-ray polarimetry

Posted by dbos Stanford

Kavli Affiliate: Nicola Omodei | First 5 Authors: Riccardo Ferrazzoli, Dmitry Prokhorov, Niccolò Bucciantini, Patrick Slane, Jacco Vink | Summary: Supernova remnants (SNRs) provide insights into cosmic-ray acceleration and magnetic field dynamics at shock fronts. Recent X-ray polarimetric measurements by the Imaging X-ray Polarimetry Explorer (IXPE) have revealed radial magnetic fields near particle acceleration sites […]

A systematic study of the ultra-fast outflow responses to luminosity variations in active galactic nuclei

Posted by dbos MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Yerong Xu, Ciro Pinto, Daniele Rogantini, Didier Barret, Stefano Bianchi | Summary: The extreme velocities and high ionization states of ultra-fast outflows (UFOs) make them a promising candidate for AGN feedback on the evolution of the host galaxy. However, their exact underlying driving mechanism is not yet […]

Search for lepton-flavor-violating $τ^- to μ^-μ^+μ^-$ decays at Belle II

Posted by dbos Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Aihara, N. Akopov | Summary: We present the result of a search for the charged-lepton-flavor violating decay $tau^- to mu^-mu^+mu^-$ using a $424fb^{-1}$ sample of data recorded by the Belle II experiment at the SuperKEKB $e^{-}e^{+}$ collider. The selection […]

TOI-2447 b / NGTS-29 b: a 69-day Saturn around a Solar analogue

Posted by dbos MIT

Kavli Affiliate: Sara Seager | First 5 Authors: Samuel Gill, Daniel Bayliss, Solène Ulmer-Moll, Peter J. Wheatley, Rafael Brahm | Summary: Discovering transiting exoplanets with relatively long orbital periods ($>$10 days) is crucial to facilitate the study of cool exoplanet atmospheres ($T_{rm eq} < 700 K$) and to understand exoplanet formation and inward migration further […]

On the energy budget of starquake-induced repeating fast radio bursts

Posted by dbos Peking

Kavli Affiliate: Renxin Xu | First 5 Authors: Wei-Yang Wang, Chen Zhang, Enping Zhou, Xiaohui Liu, Jiarui Niu | Summary: With a growing sample of fast radio bursts (FRBs), we investigate the energy budget of different power sources within the framework of magnetar starquake triggering mechanism. During a starquake, the energy can be released in […]
