Kavli Affiliate: George Efstathiou | First 5 Authors: Itamar Reis, Rennan Barkana, Anastasia Fialkov, , | Summary: The 21-cm signal from cosmic dawn and the epoch of reionization (EoR) probes the characteristics of the high redshift galaxy population. Many of the astrophysical properties of galaxies at high redshifts are currently unconstrained due to the lack […]
Kavli Affiliate: Gregory Herczeg | First 5 Authors: Jeong-Eun Lee, Sieun Lee, Seonjae Lee, Kyung-Won Suh, Se-Hyung Cho | Summary: AGBs and YSOs often share the same domains in IR color-magnitude or color-color diagrams leading to potential mis-classification. We extracted a list of AGB interlopers from the published YSO catalogues using the periodogram analysis on […]
Kavli Affiliate: Brian Nord | First 5 Authors: Adam Shandonay, Robert Morgan, Keith Bechtol, Clecio R. Bom, Brian Nord | Summary: Searches for counterparts to multimessenger events with optical imagers use difference imaging to detect new transient sources. However, even with existing artifact detection algorithms, this process simultaneously returns several classes of false positives: false […]
Kavli Affiliate: C. L. Kuo | First 5 Authors: J. A. Sobrin, A. J. Anderson, A. N. Bender, B. A. Benson, D. Dutcher | Summary: SPT-3G is the third survey receiver operating on the South Pole Telescope dedicated to high-resolution observations of the cosmic microwave background (CMB). Sensitive measurements of the temperature and polarization anisotropies […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Vidya Muthukumar, Christos Thrampoulidis, , | Summary: The literature on "benign overfitting" in overparameterized models has been mostly restricted to regression or binary classification; however, modern machine learning operates in the multiclass setting. Motivated by this discrepancy, we study benign overfitting in multiclass linear classification. […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Csaba Csáki, Andrew Gomes, Hitoshi Murayama, Ofri Telem, | Summary: We demonstrate that $SO(N_{c})$ gauge theories with matter fields in the vector representation confine due to monopole condensation and break the $SU(N_{F})$ chiral symmetry to $SO(N_{F})$ via the quark bilinear. Our results are obtained by perturbing the […]
Kavli Affiliate: Tom Abel | First 5 Authors: Santi Roca-Fàbrega, Ji-hoon Kim, Loic Hausammann, Kentaro Nagamine, Johnny W. Powell | Summary: We present a suite of high-resolution cosmological zoom-in simulations to $z=4$ of a $10^{12},{rm M}_{odot}$ halo at $z=0$, obtained using seven contemporary astrophysical simulation codes widely used in the numerical galaxy formation community. Physics […]
Kavli Affiliate: Scott A. Hughes | First 5 Authors: Enrico Barausse, Emanuele Berti, Vitor Cardoso, Scott A. Hughes, Gaurav Khanna | Summary: A powerful technique to calculate gravitational radiation from binary systems involves a perturbative expansion: if the masses of the two bodies are very different, the "small" body is treated as a point particle […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Andrey Kravtsov, Viraj Manwadkar, , , | Summary: We present a simple regulator-type framework designed specifically for modelling formation of dwarf galaxies. We explore sensitivity of model predictions for the stellar mass–halo mass and stellar mass–metallicity relations to different modelling choices and parameter values. Despite its simplicity, […]
Kavli Affiliate: Kejia Lee | First 5 Authors: Ligong Bian, Rong-Gen Cai, Shuo Cao, Zhoujian Cao, He Gao | Summary: It has been a half-decade since the first direct detection of gravitational waves, which signifies the coming of the era of the gravitational-wave astronomy and gravitational-wave cosmology. The increasing number of the detected gravitational-wave events […]
