Kavli Affiliate: Sara Seager | First 5 Authors: Daniel Valentine, Hannah R. Wakeford, Ryan C. Challener, Natasha E. Batalha, Nikole K. Lewis | Summary: We present the first spectroscopic characterisation of the dayside atmosphere of WASP-17b in the mid-infrared using a single JWST MIRI/LRS eclipse observation. From forward-model fits to the 5-12 $mu$m emission spectrum, […]
Kavli Affiliate: Wei Gao | First 5 Authors: Zhiyi Pan, Wei Gao, Shan Liu, Ge Li, | Summary: Despite alleviating the dependence on dense annotations inherent to fully supervised methods, weakly supervised point cloud semantic segmentation suffers from inadequate supervision signals. In response to this challenge, we introduce a novel perspective that imparts auxiliary constraints […]
Kavli Affiliate: Max Tegmark | First 5 Authors: David D. Baek, Yuxiao Li, Max Tegmark, , | Summary: Motivated by interpretability and reliability, we investigate how neural networks represent knowledge during graph learning, We find hints of universality, where equivalent representations are learned across a range of model sizes (from $10^2$ to $10^9$ parameters) and […]
Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Timing Yang, Yaodong Yu, Sucheng Ren, Guoyizhe Wei | Summary: In this work, we present a comprehensive analysis of causal image modeling and introduce the Adventurer series models where we treat images as sequences of patch tokens and employ uni-directional language models to learn visual […]
Kavli Affiliate: John E. Bowers | First 5 Authors: Shixin Xue, Mingxiao Li, Raymond Lopez-rios, Jingwei Ling, Zhengdong Gao | Summary: The invention of the laser unleashed the potential of optical metrology, leading to numerous advancements in modern science and technology. This reliance on lasers, however, also sets a bottleneck for precision optical metrology which […]
Kavli Affiliate: Lijing Shao | First 5 Authors: Alexander W. Raymond, Sheperd S. Doeleman, Keiichi Asada, Lindy Blackburn, Geoffrey C. Bower | Summary: The first very long baseline interferometry (VLBI) detections at 870$mu$m wavelength (345$,$GHz frequency) are reported, achieving the highest diffraction-limited angular resolution yet obtained from the surface of the Earth, and the highest-frequency […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Peter G. Boorman, Daniel Stern, Roberto J. Assef, Abhijeet Borkar, Murray Brightman | Summary: Recent models suggest approximately half of all accreting supermassive black holes (SMBHs; $M_{rm BH}$ $gtrsim$ 10$^{5}$ M$_{odot}$) are expected to undergo intense growth phases behind Compton-thick ($N_{rm H}$ $>$ 1.5 $times$ 10$^{24}$ cm$^{-2}$) […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Peter G. Boorman, Poshak Gandhi, Johannes Buchner, Daniel Stern, Claudio Ricci | Summary: Hard X-ray-selected samples of Active Galactic Nuclei (AGN) provide one of the cleanest views of supermassive black hole accretion, but are biased against objects obscured by Compton-thick gas column densities of $N_{rm H}$ $>$ […]
Kavli Affiliate: Peter Graham | First 5 Authors: Zachary Bogorad, Peter Graham, Harikrishnan Ramani, , | Summary: Dark matter’s existence is known thanks to its gravitational interaction with Standard Model particles, but it remains unknown whether this is the only force present between them. While many searches for such new interactions with dark matter focus […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Kaitlyn Shin, Calvin Leung, Sunil Simha, Bridget C. Andersen, Emmanuel Fonseca | Summary: Fast radio bursts (FRBs) are unique probes of extragalactic ionized baryonic structure as each signal, through its burst properties, holds information about the ionized matter it encounters along its sightline. FRB 20200723B is […]
