BICEP / Keck XVII: Line of Sight Distortion Analysis: Estimates of Gravitational Lensing, Anisotropic Cosmic Birefringence, Patchy Reionization, and Systematic Errors

Posted by Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: BICEP/Keck Collaboration, :, P. A. R. Ade, Z. Ahmed, M. Amiri | Summary: We present estimates of line-of-sight distortion fields derived from the 95 GHz and 150 GHz data taken by BICEP2, BICEP3, and Keck Array up to the 2018 observing season, leading to cosmological constraints and […]

High-energy neutrino emission from magnetised jets of rapidly rotating protomagnetars

Posted by klaurent Tokyo

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Mukul Bhattacharya, Jose Alonso Carpio, Kohta Murase, Shunsaku Horiuchi, | Summary: Relativistic jets originating from protomagnetar central engines can lead to long duration gamma-ray bursts (GRBs) and are considered potential sources of ultrahigh-energy cosmic rays and secondary neutrinos. We explore the propagation of such jets through a […]

A dense mini-Neptune orbiting the bright young star HD 18599

Posted by klaurent MIT

Kavli Affiliate: Avi Shporer | First 5 Authors: Jose I. Vines, James S. Jenkins, Zaira Berdiñas, Maritza G. Soto, Matías R. Díaz | Summary: Very little is known about the young planet population because the detection of small planets orbiting young stars is obscured by the effects of stellar activity and fast rotation which mask […]

Periodic Artifact Reduction in Fourier transforms of Full Field Atomic Resolution Images

Posted by klaurent Cornell

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Robert Hovden, Yi Jiang, Huolin L. Xin, Lena F. Kourkoutis, | Summary: The discrete Fourier transform is among the most routine tools used in high-resolution scanning / transmission electron microscopy (S/TEM). However, when calculating a Fourier transform, periodic boundary conditions are imposed and sharp discontinuities between […]

Using Host Galaxy Photometric Redshifts to Improve Cosmological Constraints with Type Ia Supernova in the LSST Era

Posted by Chicago

Kavli Affiliate: Richard Kessler | First 5 Authors: Ayan Mitra, Richard Kessler, Surhud More, Renee Hlozek, The LSST Dark Energy Science Collaboration | Summary: We perform a rigorous cosmology analysis on simulated type Ia supernovae (SN~Ia) and evaluate the improvement from including photometric host-galaxy redshifts compared to using only the "zspec" subset with spectroscopic redshifts […]

Spatiotemporal Classification with limited labels using Constrained Clustering for large datasets

Posted by klaurent Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Praveen Ravirathinam, Rahul Ghosh, Ke Wang, Keyang Xuan, Ankush Khandelwal | Summary: Creating separable representations via representation learning and clustering is critical in analyzing large unstructured datasets with only a few labels. Separable representations can lead to supervised models with better classification capabilities and additionally aid in […]
