Low-energy Explosions in a Gravitational Field: Implications for Sub-energetic Supernovae and Fast X-ray Transients

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 […]

JWST-TST High Contrast: Achieving direct spectroscopy of faint substellar companions next to bright stars with the NIRSpec IFU

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, […]

TOI-5126: A hot super-Neptune and warm Neptune pair discovered by $textit{TESS}$ and $textit{CHEOPS}$

Kavli Affiliate: Sara Seager | First 5 Authors: Tyler R. Fairnington, Emma Nabbie, Chelsea X. Huang, George Zhou, Orion Foo | Summary: We present the confirmation of a hot super-Neptune with an exterior Neptune companion orbiting a bright (V = 10.1 mag) F-dwarf identified by the $textit{Transiting Exoplanet Survey Satellite}$ ($textit{TESS}$). The two planets, observed […]

JWST-TST DREAMS: Quartz Clouds in the Atmosphere of WASP-17b

Kavli Affiliate: Sara Seager | First 5 Authors: David Grant, Nikole K. Lewis, Hannah R. Wakeford, Natasha E. Batalha, Ana Glidden | Summary: Clouds are prevalent in many of the exoplanet atmospheres that have been observed to date. For transiting exoplanets, we know if clouds are present because they mute spectral features and cause wavelength-dependent […]

Extreme mass-ratio inspiral and waveforms for a spinning body into a Kerr black hole via osculating geodesics and near-identity transformations

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Lisa V. Drummond, Philip Lynch, Alexandra G. Hanselman, Devin R. Becker, Scott A. Hughes | Summary: Understanding the orbits of spinning bodies in curved spacetime is important for modeling binary black hole systems with small mass ratios. At zeroth order in mass ratio, the smaller body […]

How time weathers galaxies: The temporal impact of the cluster environment on galaxy formation and evolution

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Stephanie O’Neil, Josh Borrow, Mark Vogelsberger, Hanzhang Zhao, Bing Wang | Summary: We illuminate the altered evolution of galaxies in clusters compared to the field by tracking galaxies in the IllustrisTNG300 simulation as they enter isolated clusters of mass $10^{13} < M_{rm 200, mean} / {rm M}_odot […]
