Flat to nonflat: Calculating nonlinear power spectra of biased tracers for nonflat $Λ$CDM model

Posted by dbos Tokyo

Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryo Terasawa, Ryuichi Takahashi, Takahiro Nishimichi, Masahiro Takada, | Summary: The growth of large-scale structure, together with the geometrical information of cosmic expansion history and cosmological distances, can be used to obtain constraints on the spatial curvature of the universe that probes the early universe physics, whereas […]

Water-Rich Disks around Late M-stars Unveiled: Exploring the Remarkable Case of Sz114

Posted by dbos October 20, 2023Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Chengyan Xie, Ilaria Pascucci, Feng Long, Klaus M. Pontoppidan, Andrea Banzatti | Summary: We present an analysis of the JWST/MIRI-MRS spectrum of Sz114, an accreting M5 star surrounded by a large dust disk with a gap at ~39au. The spectrum is molecular-rich: we report the detection […]

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Chengyan Xie, Ilaria Pascucci, Feng Long, Klaus M. Pontoppidan, Andrea Banzatti | Summary: We present an analysis of the JDISC JWST/MIRI-MRS spectrum of Sz~114, an accreting M5 star surrounded by a large dust disk with a shallow gap at $sim 39$ au. The spectrum is molecular-rich: […]

Adaptive Fine-tuning based Transfer Learning for the Identification of MGMT Promoter Methylation Status

Posted by dbos October 18, 2023October 30, 2023Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Erich Schmitz, Yunhui Guo, Jing Wang, , | Summary: Glioblastoma Multiforme (GBM) is an aggressive form of malignant brain tumor with a generally poor prognosis. Treatment usually includes a mix of surgical resection, radiation therapy, and akylating chemotherapy but, even with these intensive treatments, the 2-year survival […]

Galaxy formation with Wave/Fuzzy Dark Matter: The core-halo structure

Posted by dbos October 18, 2023October 30, 2023MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Alvaro Pozo, Razieh Emami, Philip Mocz, Tom Broadhurst, Lars Hernquist | Summary: Dark matter-dominated cores have long been claimed for the well-studied local group dwarf galaxies. More recently, extended stellar halos have been uncovered around several of these dwarfs through deeper imaging and spectroscopy. Such core-halo structures […]

A Population of Short-duration Gamma-ray Bursts with Dwarf Host Galaxies

Posted by dbos October 18, 2023October 30, 2023Chicago

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Anya E. Nugent, Wen-fai Fong, Cristian Castrejon, Joel Leja, Michael Zevin | Summary: We present a population of 11 of the faintest ($> 25.5$ AB mag) short gamma-ray burst (GRB) host galaxies. We model their sparse available observations using the stellar population inference code Prospector-$beta$ and […]
