GRB Redshift Estimation using Machine Learning and the Associated Web-App

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Aditya Narendra, Maria Dainotti, Milind Sarkar, Aleksander Lenart, Malgorzata Bogdan | Summary: Context. Gamma-ray bursts (GRBs), observed at redshifts as high as 9.4, could serve as valuable probes for investigating the distant Universe. However, this necessitates an increase in the number of GRBs with determined redshifts, as […]

Machine-Learning Analysis of Radiative Decays to Dark Matter at the LHC

Kavli Affiliate: Marcela Carena | First 5 Authors: Ernesto Arganda, Marcela Carena, Martín de los Rios, Andres D. Perez, Duncan Rocha | Summary: The search for weakly interacting matter particles (WIMPs) is one of the main objectives of the High Luminosity Large Hadron Collider (HL-LHC). In this work we use Machine Learning (ML) techniques to […]

The Affleck-Dine Curvaton

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Aurora Ireland, Gordan Krnjaic, Takuya Okawa, , | Summary: The Standard Model of particle physics does not explain the origin of the universe’s baryon asymmetry or its primordial fluctuations. The Affleck-Dine mechanism is a well-motivated scenario for generating the baryon asymmetry through the post-inflationary dynamics of a […]

Connection between Non-Axisymmetric Structures and Neutral Gas Distribution in Disk Galaxies

Kavli Affiliate: Luis C. Ho | First 5 Authors: Ze-Zhong Liang, Jing Wang, Hua Gao, Luis C. Ho, E. Athanassoula | Summary: Non-axisymmetric structures, such as bars and spiral arms, are known to concentrate molecular gas and star formation in galaxy centers, actively building up the pseudo-bulges. However, a direct link between the neutral (i.e., […]

Towards Better Performance in Incomplete LDL: Addressing Data Imbalance

Kavli Affiliate: Jing Wang | First 5 Authors: Zhiqiang Kou, Haoyuan Xuan, Jing Wang, Yuheng Jia, Xin Geng | Summary: Label Distribution Learning (LDL) is a novel machine learning paradigm that addresses the problem of label ambiguity and has found widespread applications. Obtaining complete label distributions in real-world scenarios is challenging, which has led to […]

Most High-density Exoplanets Are Unlikely to Be Remnant Giant-planet Cores

Kavli Affiliate: Sara Seager | First 5 Authors: Zifan Lin, Saverio Cambioni, Sara Seager, , | Summary: Some exoplanets have much higher densities than expected from stellar abundances of planet-forming elements. There are two theories – metal-rich formation hypothesis and naked core hypothesis – that explain how formation and evolution can alter the compositions and […]

Spectrum Sharing using Deep Reinforcement Learning in Vehicular Networks

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Riya Dinesh Deshpande, Faheem A. Khan, Qasim Zeeshan Ahmed, , | Summary: As the number of devices getting connected to the vehicular network grows exponentially, addressing the numerous challenges of effectively allocating spectrum in dynamic vehicular environment becomes increasingly difficult. Traditional methods may not suffice to tackle […]

Dynamical time and Ashtekar variables for the Husain-Kuchař model

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Juan Margalef-Bentabol, Aitor Vicente-Cano, Eduardo J. S. Villaseñor, | Summary: The relation between the Husain-Kuchav{r} model and some extensions thereof that incorporate a dynamical time variable is explored. To this end, we rely on the geometric approach to the Hamiltonian dynamics of […]
