The Missing Hard Photons of Little Red Dots: Their Incident Ionizing Spectra Resemble Massive Stars

Posted by klaurent Peking

Kavli Affiliate: Kohei Inayoshi | Summary:The nature of Little Red Dots (LRDs) has largely been investigated through their continuum emission, with lines assumed to arise from a broad-line region. In this paper, we instead use recombination lines to infer the intrinsic properties of the central engine. Our analysis first reveals a tension between the ionizing […]

Constraints on Long-Range Forces in De Sitter Space

Posted by klaurent Chicago

Kavli Affiliate: Austin Joyce | Summary:The representation theory of de Sitter space admits partially massless (PM) particles, but whether such particles can participate in consistent interacting theories remains unclear. We investigate the consistency of theories containing PM fields, particularly when these fields are coupled to gravity. Our strategy exploits the fact that PM fields correspond […]

VLT/MUSE Detection of the AB Aurigae b Protoplanet with $H _rm α$ Spectroscopy

Posted by klaurent Peking

Kavli Affiliate: Ruobing Dong | Summary:We analyze high-contrast, medium-spectral-resolution $H_rm α$ observations of the star AB Aurigae using the Very Large Telescope’s Multi Unit Spectroscopic Explorer (MUSE). In multiple epochs, MUSE detects the AB Aur b protoplanet discovered from Subaru/SCExAO data in emission at wavelengths slightly blue-shifted from the $H_rm α$ line center (i.e. at […]

Enriched volatiles and refractories but deficient titanium on the dayside atmosphere of WASP-121b revealed by JWST/NIRISS

Posted by klaurent Chicago

Kavli Affiliate: Michael Turner| First 5 Authors: Stefan Pelletier, Stefan Pelletier, , , | Summary:With dayside temperatures elevated enough for all atmospheric constituents to be present in gas form, ultra-hot Jupiters offer a unique opportunity to probe the composition of giant planets. We aim to infer the composition and thermal structure of the dayside atmosphere […]

Rapid rebalancing of co-tuned ensemble activity in the auditory cortex

Posted by dbos Hopkins

Kavli Affiliate: Patrick Kanold | Authors: HiJee Kang, Travis Babola and Patrick O Kanold | Summary: Sensory information is represented by small neuronal ensembles in sensory cortices. Neuronal activity shows high trial-by-trial variability in that repeated presentation of the same stimulus, e. g., multiple presentations of the same sound activate differing ensembles in the auditory […]

Three-dimensional hyperspectral imaging with optical microcombs

Posted by klaurent Caltech

Kavli Affiliate: Kerry Vahala | Summary:Optical frequency combs have revolutionised time and frequency metrology [1, 2]. The advent of microresonator-based frequency combs (‘microcombs’ [3-5]) is set to lead to the miniaturisation of devices that are ideally suited to a wide range of applications, including microwave generation [6, 7], ranging [8-10], the precise calibration of astronomical […]

Deep Learning Improves Parameter Estimation in Reinforcement Learning Models

Posted by dbos UCSD / Salk

Kavli Affiliate: Marcelo Mattar | Authors: Hua-Dong Xiong, Li Ji-An, Marcelo G Mattar and Robert C Wilson | Summary: Cognitive models are widely used in psychology and neuroscience to formulate and test hypotheses about cognitive processes. These processes are characterized by model parameters, which are then used for scientific inference. The reliability of scientific conclusions […]

Few-shot Unknown Class Discovery of Hyperspectral Images with Prototype Learning and Clustering

Posted by klaurent Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: Chun Liu, Chun Liu, , , | Summary: Open-set few-shot hyperspectral image (HSI) classification aims to classify image pixels by using few labeled pixels per class, where the pixels to be classified may be not all from the classes that have been seen. To address the open-set […]

Copas-Jackson-type bounds for publication bias over a general class of selection models

Posted by klaurent UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Taojun Hu, Taojun Hu, , , | Summary: Publication bias (PB) is one of the most vital threats to the accuracy of meta-analysis. Adjustment or sensitivity analysis based on selection models, which describe the probability of a study being published, provide a more objective evaluation of PB […]
