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

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

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

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 […]

Radiation hydrodynamical simulations of super-Eddington mass transfer and black hole growth in close binaries

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Daisuke Toyouchi, Kenta Hotokezaka, Kohei Inayoshi, Rolf Kuiper, | Summary: Radiation-driven outflows play a crucial role in extracting mass and angular momentum from binary systems undergoing rapid mass transfer at super-Eddington rates. To study the mass transfer process from a massive donor star to a stellar-mass black […]

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

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 […]
