Kavli Affiliate: Dheeraj Pasham | First 5 Authors: Yukta Ajay, Muryel Guolo, Dheeraj Pasham, , | Summary: We present multiwavelength analyses of an active optical transient AT2021fxu which shows the appearance of previously absent broad emission lines in a recent optical spectrum, suggesting a Changing-look (CL) Active Galactic Nucleus (AGN). During the spectral transition, the […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Josh Borrow, Rahul Kannan, Enrico Garaldi, Aaron Smith, Mark Vogelsberger | Summary: Early galaxies were the radiation source for reionization, with the photoheating feedback from the reionization process expected to reduce the efficiency of star formation in low mass haloes. Hence, to fully understand reionization and galaxy […]

Kavli Affiliate: Ronald Remillard | First 5 Authors: Dheeraj R. Pasham, Matteo Lucchini, Tanmoy Laskar, Benjamin P. Gompertz, Shubham Srivastav | Summary: A black hole can launch a powerful relativistic jet after it tidally disrupts a star. If this jet fortuitously aligns with our line of sight, the overall brightness is Doppler boosted by several […]
Kavli Affiliate: David Principe | First 5 Authors: Philipp Weber, Sebastián Pérez, Greta Guidi, Nicolás T. Kurtovic, Alice Zurlo | Summary: Dense stellar environments as hosts of ongoing star formation increase the probability of gravitational encounters among stellar systems during the early stages of evolution. Stellar interaction may occur through non-recurring, hyperbolic or parabolic passages […]

Kavli Affiliate: George Clark | First 5 Authors: Stefan Duling, Joachim Saur, George Clark, Frederic Allegrini, Thomas Greathouse | Summary: On June 7th, 2021 the Juno spacecraft visited Ganymede and provided the first in situ observations since Galileo’s last flyby in 2000. The measurements obtained along a one-dimensional trajectory can be brought into global context […]
Kavli Affiliate: Eric D. Miller | First 5 Authors: Ralph Kraft, Maxim Markevitch, Caroline Kilbourne, Joseph S. Adams, Hiroki Akamatsu | Summary: The Line Emission Mapper (LEM) is an X-ray Probe for the 2030s that will answer the outstanding questions of the Universe’s structure formation. It will also provide transformative new observing capabilities for every […]
