Effects of galactic environment on size and dark matter content in low-mass galaxies

Kavli Affiliate: Lina Necib | First 5 Authors: Francisco J. Mercado, Jorge Moreno, Robert Feldmann, Marckie Zeender, Jose A. Benavides Blanco | Summary: We utilize the cosmological volume simulation, FIREbox, to investigate how a galaxy’s environment influences its size and dark matter content. Our study focuses on approximately 1,200 galaxies (886 central and 332 satellite […]

Time-resolved Hubble Space Telescope UV observations of an X-ray quasi-periodic eruption source

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Thomas Wevers, Muryel Guolo, Sean Lockwood, Andrew Mummery, Dheeraj R. Pasham | Summary: X-ray quasi-periodic eruptions (QPEs) are a novel mode of variability in nearby galactic nuclei whose origin remains unknown. Their multi-wavelength properties are poorly constrained, as studies have focused almost entirely on the X-ray […]

Enhanced Condensation Through Rotation

Kavli Affiliate: Frank Wilczek | First 5 Authors: Maxim Chernodub, Frank Wilczek, , , | Summary: We argue that the rotation of a thin superconducting cylinder can increase the critical temperature of the superconducting phase transition substantially. The phenomenon can be interpreted as an effective negative moment of inertia associated with condensation of Cooper pairs. […]

Millihertz Oscillations Near the Innermost Orbit of a Supermassive Black Hole

Kavli Affiliate: Erin Kara | First 5 Authors: Megan Masterson, Erin Kara, Christos Panagiotou, William N. Alston, Joheen Chakraborty | Summary: Recent discoveries from time-domain surveys are defying our expectations for how matter accretes onto supermassive black holes (SMBHs). The increased rate of short-timescale, repetitive events around SMBHs, including the newly-discovered quasi-periodic eruptions (QPEs), are […]
