Kavli Affiliate: Max Tegmark | First 5 Authors: Eric J. Michaud, Ziming Liu, Uzay Girit, Max Tegmark, | Summary: We propose the Quantization Model of neural scaling laws, explaining both the observed power law dropoff of loss with model and data size, and also the sudden emergence of new capabilities with scale. We derive this […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Xiaowei Ou, Anna-Christina Eilers, Lina Necib, Anna Frebel, | Summary: In this paper, we construct the circular velocity curve of the Milky Way out to $sim 30$ kpc, providing an updated model of the dark matter density profile. We derive precise parallaxes for 120,309 stars with a […]
Kavli Affiliate: Srijit Goswami | First 5 Authors: Máté Kedves, Bálint Szentpéteri, Albin Márffy, Endre Tóvári, Nikos Papadopoulos | Summary: Bilayer graphene (BLG) was recently shown to host a band-inverted phase with unconventional topology emerging from the Ising-type spin–orbit interaction (SOI) induced by the proximity of transition metal dichalcogenides with large intrinsic SOI. Here, we […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Yi Xu, Masami Ouchi, Yuki Isobe, Kimihiko Nakajima, Shinobu Ozaki | Summary: We present demography of the dynamics and gas-mass fraction of 33 extremely metal-poor galaxies (EMPGs) with metallicities of $0.015-0.195~Z_odot$ and low stellar masses of $10^4-10^8~M_odot$ in the local universe. We conduct deep optical integral-field spectroscopy […]
Kavli Affiliate: Eli Rykoff | First 5 Authors: Chun-Hao To, Joseph DeRose, Risa H. Wechsler, Eli Rykoff, Hao-Yi Wu | Summary: We present the Cardinal mock galaxy catalogs, a new version of the Buzzard simulation that has been updated to support ongoing and future cosmological surveys, including DES, DESI, and LSST. These catalogs are based […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Jakub Podgorny, Lorenzo Marra, Fabio Muleri, Nicole Rodriguez Cavero, Ajay Ratheesh | Summary: We report on an X-ray polarimetric observation of the high-mass X-ray binary LMC X-1 in the high/soft state, obtained by the Imaging X-ray Polarimetry Explorer (IXPE) in October 2022. The measured polarization is […]
Kavli Affiliate: Jia Liu | First 5 Authors: Haisong Liu, Tao Lu, Yihui Xu, Jia Liu, Limin Wang | Summary: In this paper, we study the problem of jointly estimating the optical flow and scene flow from synchronized 2D and 3D data. Previous methods either employ a complex pipeline that splits the joint task into […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Zhaosheng Li, Lucien Kuiper, Mingyu Ge, Maurizio Falanga, Juri Poutanen | Summary: We studied the broadband X-ray timing and spectral behaviors of the newly confirmed accreting millisecond X-ray pulsar MAXI J1816$-$195 during its 2022 outburst. We used the data from Insight-HXMT ME/HE, NICER and NuSTAR which cover […]
Kavli Affiliate: Erin Kara | First 5 Authors: Honghui Liu, Jiachen Jiang, Zuobin Zhang, Cosimo Bambi, Andrew C. Fabian | Summary: We present a high-density relativistic reflection analysis of 21 spectra of six black hole X-ray binaries in the hard state with data from textit{NuSTAR} and textit{Swift}. We find that 76% of the observations in […]
Kavli Affiliate: Jing Wang | First 5 Authors: , , , , | Summary: We investigate the parameter regimes favourable for the emergence of plasmons in isotropic, anisotropic, and band-mass symmetric and asymmetric Luttinger semimetals (LSMs). An LSM harbours a quadratic band-crossing point (QBCP) in its bandstructure, where the upper and lower branches of dispersion […]
