TOI-6478 b: a cold under-dense Neptune transiting a fully convective M dwarf from the thick disc

Kavli Affiliate: Avi Shporer | First 5 Authors: Madison G. Scott, Amaury H. M. J. Triaud, Khalid Barkaoui, Daniel Sebastian, Adam J. Burgasser | Summary: Growing numbers of exoplanet detections continue to reveal the diverse nature of planetary systems. Planet formation around late-type M dwarfs is of particular interest. These systems provide practical laboratories to […]

A persistent disk wind and variable jet outflow in the neutron-star low-mass X-ray binary GX 13+1

Kavli Affiliate: Norbert Schulz | First 5 Authors: Daniele Rogantini, Jeroen Homan, Richard M. Plotkin, Maureen van den Berg, James Miller-Jones | Summary: In low-mass X-ray binaries (LMXBs), accretion flows are often associated with either jet outflows or disk winds. Studies of LMXBs with luminosities up to roughly 20% of the Eddington limit indicate that […]

Novel Polarimetric Analysis of Near Horizon Flaring Episodes in M87* in Millimeter Wavelength

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Razieh Emami, Matthew Liska, Koushik Chatterjee, Geoffrey C. Bower, Wystan Benbow | Summary: Recent multi-wavelength observations of M87* citep{2024A&A…692A.140A} revealed a high-energy $gamma$-ray flare without a corresponding millimeter counterpart. We present a theoretical polarimetric study to evaluate the presence and nature of a potential millimeter flare in […]

Recursive Training Loops in LLMs: How training data properties modulate distribution shift in generated data?

Kavli Affiliate: Peter Ford | First 5 Authors: Grgur Kovač, Jérémy Perez, Rémy Portelas, Peter Ford Dominey, Pierre-Yves Oudeyer | Summary: Large language models (LLMs) are increasingly contributing to the creation of content on the Internet. This creates a feedback loop as subsequent generations of models will be trained on this generated, synthetic data. This […]

Evidence for Charge Exchange Emission in Supernova Remnant N132D from XRISM/Resolve Observations

Kavli Affiliate: Eric D. Miller | First 5 Authors: Liyi Gu, Hiroya Yamaguchi, Adam Foster, Satoru Katsuda, Hiroyuki Uchida | Summary: XRISM has delivered one of its first light observations on N132D, the X-ray brightest supernova remnant in the Large Magellanic Cloud. Utilizing 193 ks of high-resolution X-ray spectroscopy data, we conduct a comprehensive search […]

Ain’t no resonance high enough: Core collapse in self-interacting dark matter across two decades in halo mass

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Vinh Tran, Xuejian Shen, Daniel Gilman, Mark Vogelsberger, Stephanie O’Neil | Summary: Core collapse, a process associated with self-interacting dark matter (SIDM) models, can increase the central density of halos by orders of magnitude with observable consequences for dwarf galaxy properties and gravitational lensing. Resonances in the […]

Supersizing hydrodynamical simulations of reionization using perturbative techniques

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Wenzer Qin, Katelin Schutz, Olivia Rosenstein, Stephanie O’Neil, Mark Vogelsberger | Summary: We show that perturbative techniques inspired by effective field theory (EFT) can be used to "paint on" the 21~cm field during reionization using only the underlying linear density field. This procedure is accurate to within […]
