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 […]

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 […]

Advancing Precision Particle Background Estimation for Future X-ray Missions: Correlated Variability between AMS and Chandra/XMM-Newton

Kavli Affiliate: Eric D. Miller | First 5 Authors: Arnab Sarkar, Catherine E. Grant, Eric D. Miller, Mark Bautz, Benjamin Schneider | Summary: Galactic cosmic ray (GCR) particles have a significant impact on the particle-induced background of X-ray observatories, and their flux exhibits substantial temporal variability, potentially influencing background levels. In this study, we present […]

Probability of Presence Versus $ψ(x,t)^* ψ(x, t)$

Kavli Affiliate: Frank Wilczek | First 5 Authors: Frank Wilczek, Zara Yu, , , | Summary: Postulating the identification of $psi^*(x, t) psi(x,t)$ with a physical probability density is unsatisfactory conceptually and overly limited practically. For electrons, there is a simple, calculable relativistic correction proportional to $nabla psi^* cdot nabla psi$. In particular, zeroes of […]
