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 3-5 um at moderate spectral resolution (R~2,700) and thereby better constrain the composition, disequilibrium […]

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 […]

Growing Brains: Co-emergence of Anatomical and Functional Modularity in Recurrent Neural Networks

Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Mikail Khona, Ila R. Fiete, Max Tegmark, | Summary: Recurrent neural networks (RNNs) trained on compositional tasks can exhibit functional modularity, in which neurons can be clustered by activity similarity and participation in shared computational subtasks. Unlike brains, these RNNs do not exhibit anatomical modularity, […]

Variability as a predictor for the hard-to-soft state transition in GX 339-4

Kavli Affiliate: Erin Kara | First 5 Authors: Matteo Lucchini, Marina Ten Have, Jingyi Wang, Jeroen Homan, Erin Kara | Summary: During the outbursts of black hole X-ray binaries (BHXRBs), their accretion flows transition through several states. The source luminosity rises in the hard state, dominated by non-thermal emission, before transitioning to the blackbody-dominated soft […]
