Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Ryan Cloutier, Michael Greklek-McKeon, Serena Wurmser, Collin Cherubim, Erik Gillis | Summary: Is the population of close-in planets orbiting M dwarfs sculpted by thermally driven escape or is it a direct outcome of the planet formation process? A number of recent empirical results strongly suggest the latter. […]

Kavli Affiliate: Paul Schechter | First 5 Authors: Cameron Lemon, Frédéric Courbin, Anupreeta More, Paul Schechter, Raoul Cañameras | Summary: Strong gravitational lenses provide unique laboratories for cosmological and astrophysical investigations, but they must first be discovered – a task that can be met with significant contamination by other astrophysical objects and asterisms. Here we […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Alvaro Pozo, Razieh Emami, Philip Mocz, Tom Broadhurst, Lars Hernquist | Summary: Dark matter-dominated cores have long been claimed for the well-studied local group dwarf galaxies. More recently, extended stellar halos have been uncovered around several of these dwarfs through deeper imaging and spectroscopy. Such core-halo structures […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Warit Wijitworasart, Zoe de Beurs, Andrew Vanderburg, , | Summary: We present a dataset for investigating the impact of stellar activity on astrometric measurements using NASA’s Solar Dynamics Observatory (SDO) images of the Sun. The sensitivity of astrometry for detecting exoplanets is limited by stellar activity (e.g. […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Herman L. Marshall, Ioannis Liodakis, Alan P. Marscher, Niccolo Di Lalla, Svetlana G. Jorstad | Summary: We present X-ray polarimetry observations from the Imaging X-ray Polarimetry Explorer (IXPE) of three low spectral peak and one intermediate spectral peak blazars, namely 3C 273, 3C 279, 3C 454.3, […]
Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Daniel A. Paradiso, Eric R. Coughlin, Jonathan Zrake, Dheeraj R. Pasham, | Summary: Observations and theory suggest that core-collapse supernovae can span a range of explosion energies, and when sub-energetic, the shockwave initiating the explosion can decelerate to speeds comparable to the escape speed of the […]

Kavli Affiliate: Sara Seager | First 5 Authors: Jean-Baptiste Ruffio, Marshall D. Perrin, Kielan K. W. Hoch, Jens Kammerer, Quinn M. Konopacky | Summary: The JWST NIRSpec integral field unit (IFU) presents a unique opportunity to observe directly imaged exoplanets from 3-5um at moderate spectral resolution (R~2,700) and thereby better constrain the composition, disequilibrium chemistry, […]
