Hippocampus facilitates reinforcement learning under partial observability

Kavli Affiliate: Rui Costa | Authors: Dabal Pedamonti, Samia Mohinta, Martin Dimitrov, Hugo Malagon-Vina, Stephane Ciocchi and Rui Ponte Costa | Summary: Mastering navigation in environments with limited visibility is crucial for survival. Although the hippocam-pus has been associated with goal-oriented navigation, its role in real-world behaviour remains unclear. To investigate this, we combined deep […]

Cosmological Evolution of Fast Radio Bursts and The Star Formation Rate

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Sujay Champati, Vahé Petrosian, , , | Summary: We investigate the cosmological evolution of the luminosity and redshift of FRBs. As is the case for all extragalactic sources, we are dealing with data that are truncated by observational selection effects, the most important being the flux limit, […]

The radial metric function does not identify null surfaces

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Yi-Hsiung Hsu, Will Barker, Michael Hobson, Anthony Lasenby, | Summary: We investigate the conditions under which a hypersurface becomes null through the use of coordinate transformations. We demonstrate that, in static spacetimes, the correct criterion for a surface to be null is~$g_{tt} = 0$, rather than~$g^{rr} = […]

Darkness in the Crust: Searching for the truly “Dark” Subhalos with Paleo-detectors

Kavli Affiliate: Lina Necib | First 5 Authors: Xiuyuan Zhang, Lina Necib, Denis Erkal, , | Summary: Low-mass dark matter (DM) subhalos are pivotal in understanding the small-scale structure of the universe, thereby offering a sensitive method to discriminate between different cosmological models. In this study, we estimate the local number density of cold DM […]

ArtistAuditor: Auditing Artist Style Pirate in Text-to-Image Generation Models

Kavli Affiliate: Zheng Zhu | First 5 Authors: Linkang Du, Zheng Zhu, Min Chen, Zhou Su, Shouling Ji | Summary: Text-to-image models based on diffusion processes, such as DALL-E, Stable Diffusion, and Midjourney, are capable of transforming texts into detailed images and have widespread applications in art and design. As such, amateur users can easily […]

Prospects for Detecting Signs of Life on Exoplanets in the JWST Era

Kavli Affiliate: Sara Seager | First 5 Authors: Sara Seager, Luis Welbanks, Lucas Ellerbroek, William Bains, Janusz J. Petkowski | Summary: The search for signs of life in the Universe has entered a new phase with the advent of the James Webb Space Telescope (JWST). Detecting biosignature gases via exoplanet atmosphere transmission spectroscopy is in […]

WINTER on S250206dm: A near-infrared search for an electromagnetic counterpart

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Danielle Frostig, Viraj R. Karambelkar, Robert D. Stein, Nathan P. Lourie, Mansi M. Kasliwal | Summary: We present near-infrared follow-up observations of the International Gravitational Wave Network (IGWN) event S250206dm with the Wide-Field Infrared Transient Explorer (WINTER). WINTER is a near-infrared time-domain survey designed for electromagnetic […]

The Discovery of Two Quadruple Star Systems with the Second and Third Shortest Outer Periods

Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Brian P. Powell, Guillermo Torres, Veselin B. Kostov, Tamás Borkovits, Saul A. Rappaport | Summary: We present the discovery of two quadruple star systems — TIC 285853156 and TIC 392229331 — each consisting of two bound eclipsing binary stars. Among the most compact quadruples known, TIC […]
