X-ray Observations of the Peculiar Cepheid V473 Lyr Identify A Low-Mass Companion

Kavli Affiliate: Moritz Guenther | First 5 Authors: Nancy Remage Evans, Ignazio Pillitteri, Laszlo Molnar, Laszlo Szabados, Emese Plachy | Summary: V473 Lyr is a classical Cepheid which is unique in having substantial amplitude variations with a period of approximately 3.3 years, thought to be similar to the Blazhko variations in RR Lyrae stars. We […]

Photoinduced phase separation in the lead halides is a polaronic effect

Kavli Affiliate: Naomi S. Ginsberg | First 5 Authors: David T. Limmer, Naomi S. Ginsberg, , , | Summary: We present a perspective on recent observations of the photoinduced phase separation of halides in multi-component lead-halide perovskites. The spontaneous phase separation of an initial homogeneous solid solution under steady-state illumination conditions is found experimentally to […]

Effect of surface chemistry on incorporation of nanoparticles within calcite single crystals

Kavli Affiliate: Joanna Aizenberg | First 5 Authors: Giulia Magnabosco, Iryna Polishchuk, Francesco Palomba, Enrico Rampazzo, Luca Prodi | Summary: Inclusion of additives into calcite crystals allows one to embed non-native proprieties into the inorganic matrix and obtain new functional materials. Up to now, few parameters have been taken into account to evaluate the efficiency […]

Spectral analysis on standard locally homogeneous spaces

Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Fanny Kassel, Toshiyuki Kobayashi, , , | Summary: Let $X=G/H$ be a reductive homogeneous space with $H$ noncompact, endowed with a $G$-invariant pseudo-Riemannian structure. Let $L$ be a reductive subgroup of $G$ acting properly on $X$ and $Gamma$ a torsion-free discrete subgroup of $L$. Under the assumption […]

Mitigating the impact of fiber assignment on clustering measurements from deep galaxy redshift surveys

Kavli Affiliate: Naoyuki Tamura | First 5 Authors: Tomomi Sunayama, Masahiro Takada, Martin Reinecke, Ryu Makiya, Takahiro Nishimichi | Summary: We examine the impact of fiber assignment on clustering measurements from fiber-fed spectroscopic galaxy surveys. We identify new effects which were absent in previous, relatively shallow galaxy surveys such as Baryon Oscillation Spectroscopic Survey . […]

Hamiltonian deformations in quantum mechanics, $Tbar T$, and SYK

Kavli Affiliate: David J. Gross | First 5 Authors: David J. Gross, Jorrit Kruthoff, Andrew Rolph, Edgar Shaghoulian, | Summary: Motivated by $Tbar T$, we introduce and study a wide class of solvable deformations of quantum-mechanical theories. These deformations map the Hamiltonian to a function of itself. We solve these theories by computing all finite-temperature […]

It’s easy to fool yourself: Case studies on identifying bias and confounding in bio-medical datasets

Kavli Affiliate: Michael Brenner | First 5 Authors: Subhashini Venugopalan, Arunachalam Narayanaswamy, Samuel Yang, Anton Geraschenko, Scott Lipnick | Summary: Confounding variables are a well known source of nuisance in biomedical studies. They present an even greater challenge when we combine them with black-box machine learning techniques that operate on raw data. This work presents […]
