A neural model of proximity to reward

Kavli Affiliate: Costa, Rui | Authors: Paul Botros, Nuria Vendrell-Llopis, Rui Costa and Jose Carmena | Summary: Abstract Throughout learning, refinement of cortical activity in cortex, a process termed “credit assignment”, underlies the refinement of behavioral actions leading to reward. While previous research shows striatum’s role in linking behavior to reward, striatum’s role in linking […]

The Aemulus Project VI: Emulation of beyond-standard galaxy clustering statistics to improve cosmological constraints

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Kate Storey-Fisher, Jeremy Tinker, Zhongxu Zhai, Joseph DeRose, Risa H. Wechsler | Summary: There is untapped cosmological information in galaxy redshift surveys in the non-linear regime. In this work, we use the AEMULUS suite of cosmological $N$-body simulations to construct Gaussian process emulators of galaxy clustering […]

The hidden side of cosmic star formation at z > 3: Bridging optically-dark and Lyman break galaxies with GOODS-ALMA

Kavli Affiliate: John Silverman | First 5 Authors: Mengyuan Xiao, David Elbaz, Carlos Gómez-Guijarro, Lucas Leroy, Longji Bing | Summary: Our current understanding of the cosmic star formation history at z>3 is primarily based on UV-selected galaxies (i.e., LBGs). Recent studies of H-dropouts have revealed that we may be missing a large proportion of star […]

Eccentricity to the rescue! Detecting Accelerating Eccentric Binaries in the LISA Band

Kavli Affiliate: Xian Chen | First 5 Authors: Zeyuan Xuan, Smadar Naoz, Xian Chen, , | Summary: Many gravitational wave (GW) sources in the LISA band are expected to have non-negligible eccentricity. Furthermore, many of them can undergo acceleration because they reside in the presence of a tertiary. Here we develop analytical and numerical methods […]

Observational Constrains on Direct Electron Heating in Hot Accretion Flows from Sgr A* and M87*

Kavli Affiliate: Feng Yuan | First 5 Authors: Fu-Guo Xie, Ramesh Narayan, Feng Yuan, , | Summary: An important parameter in the theory of hot accretion flows around black holes is $delta$, which describes the fraction of “viscously” dissipated energy in the accretion flow that directly heats the electrons. The radiative efficiency of a hot […]

CLAD: A Contrastive Learning based Approach for Background Debiasing

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Harshitha Machiraju, Oh-Hyeon Choung, Michael Herzog, Pascal Frossard | Summary: Convolutional neural networks (CNNs) have achieved superhuman performance in multiple vision tasks, especially image classification. However, unlike humans, CNNs leverage spurious features, such as background information to make decisions. This tendency creates different problems in […]
