Magnetic Field Properties inside the Jet of Mrk 421: Multiwavelength Polarimetry Including the Imaging X-ray Polarimetry Explorer

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Dawoon E. Kim, Laura Di Gesu, Ioannis Liodakis, Alan P. Marscher, Svetlana G. Jorstad | Summary: We conducted a polarimetry campaign from radio to X-ray wavelengths of the high-synchrotron-peak (HSP) blazar Mrk 421, including Imaging X-ray Polarimetry Explorer (IXPE) measurements on 2022 December 6-8. We detected […]

Divide-and-Conquer Dynamics in AI-Driven Disempowerment

Kavli Affiliate: Max Tegmark | First 5 Authors: Peter S. Park, Max Tegmark, , , | Summary: AI companies are attempting to create AI systems that outperform humans at most economically valuable work. Current AI models are already automating away the livelihoods of some artists, actors, and writers. But there is infighting between those who […]

WD0141-675: A case study on how to follow-up astrometric planet candidates around white dwarfs

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Laura K. Rogers, John Debes, Richard J. Anslow, Amy Bonsor, S. L. Casewell | Summary: This work combines spectroscopic and photometric data of the polluted white dwarf WD0141-675 which has a now retracted astrometric super-Jupiter candidate and investigates the most promising ways to confirm Gaia astrometric planetary […]

How Nested Bars Enhance, Modulate, and are Destroyed by Gas Inflows

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Zhi Li, Min Du, Victor P. Debattista, Juntai Shen, Hui Li | Summary: Gas flows in the presence of two independently-rotating nested bars remain not fully understood, which is likely to play an important role in fueling the central black hole. We use high-resolution hydrodynamical simulations with […]

Exploring chemical enrichment of the intracluster medium with the Line Emission Mapper

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: François Mernier, Yuanyuan Su, Maxim Markevitch, Congyao Zhang, Aurora Simionescu | Summary: Synthesized in the cores of stars and supernovae, most metals disperse over cosmic scales and are ultimately deposited well outside the gravitational potential of their host galaxies. Since their presence is well visible through their […]

The Supersonic Project: Lighting up the faint end of the JWST UV luminosity function

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Claire E. Williams, William Lake, Smadar Naoz, Blakesley Burkhart, Tommaso Treu | Summary: The James Webb Space Telescope (JWST) is capable of probing extremely early eras of our Universe when the supersonic relative motions between dark matter and baryonic overdensities modulate structure formation ($z>sim 10$). We study […]

Looking in the axion mirror: An all-sky analysis of stimulated decay

Kavli Affiliate: Kiyoshi Wesley Masui | First 5 Authors: Yitian Sun, Katelin Schutz, Harper Sewalls, Calvin Leung, Kiyoshi Wesley Masui | Summary: Axion dark matter (DM) produces echo images of bright radio sources via stimulated decay. These images appear as a faint radio line centered at half the axion mass, with the line width set […]
