Peripherally automorphic unital completely positive maps
B. V. Rajarama Bhat, Samir Kar, Bharat Talwar
We identify and characterize unital completely positive (UCP) maps on finite dimensional -algebras for which the Choi-Effros product extended to the space generated by periphe…
Testing Cosmology with Double Source Lensing
Divij Sharma, Thomas E. Collett, Eric V. Linder
Double source lensing provides a dimensionless ratio of distance ratios, a "remote viewing" of cosmology through distances relative to the gravitational lens, beyond the observer.…
Fujita exponent on stratified Lie groups
Durvudkhan Suragan, Bharat Talwar
We prove that is the Fujita exponent for a semilinear heat equation on an arbitrary stratified Lie group with homogeneous dimension . This covers the Euclidean c…
Spacetime continuity and quantum information loss
Michael R. R. Good
Continuity across the shock wave of two regions in the metric during the formation of a black hole can be relaxed in order to achieve information preservation. A Planck scale sized…
Extreme electron acceleration with fixed radiation energy
Michael R. R. Good, Chiranjeeb Singha, Vasilios Zarikas
We examine the extreme situation of radiation from an electron that is asymptotically accelerated to the speed of light, resulting in finite emission energy. The analytic solution…
Gamma rays: propagation and detection
Elisa Prandini, Konstantinos Dialektopoulos, Jelena Strišković
Gamma rays constitute a privileged point of view for the study of the extreme Universe. Unlike charged cosmic rays, which are thought to have a common origin, gamma rays are not de…
Accelerated electron thermometer: observation of 1D Planck radiation
Morgan H. Lynch, Evgenii Ievlev, Michael R. R. Good
We report on the observation of thermal photons from an accelerated electron via examination of radiative beta decay of free neutrons measured by the RDK II collaboration. The emit…
Evolution of the afterglow optical spectral shape of GRB 201015A in the first hour: evidence for dust destruction
Toktarkhan Komesh, Bruce Grossan, Zhanat Maksut +3
Instruments such as the ROTSE, TORTORA, Pi of the Sky, MASTER-net, and others have recorded single-band optical flux measurements of gamma-ray bursts starting as early as $\thicksi…
Larmor Temperature, Casimir Dynamics, and Planck's Law
Evgenii Ievlev, Michael R. R. Good
Classical radiation from a single relativistically accelerating electron is investigated where the temperature characterizing the system highlights the dependence on acceleration.…
Modeling black hole evaporative mass evolution via radiation from moving mirrors
Michael R. R. Good, Alessio Lapponi, Orlando Luongo +1
We investigate the evaporation of an uncharged and non-rotating black hole (BH) in vacuum, by taking into account the effects given by the shrinking of the horizon area. These incl…
Using Host Galaxy Photometric Redshifts to Improve Cosmological Constraints with Type Ia Supernova in the LSST Era
Ayan Mitra, Richard Kessler, Surhud More +2
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 onl…
NGC 6240 Supermassive Black Hole Binary dynamical evolution based on Chandra data
M. Sobolenko, O. Kompaniiets, P. Berczik +4
The main idea of our research is to estimate the physical coalescence time of the double supermassive black hole (SMBH) system in the centre of NGC 6240 based on the X-ray observat…
Multidimensional Frank-Laptev-Weidl improvement of the Hardy Inequality
Prasun Roychowdhury, Michael Ruzhansky, Durvudkhan Suragan
We establish a new improvement of the classical -Hardy inequality on the multidimensional Euclidean space in the supercritical case. Recently, in [14], there has been a new ki…
Electromagnetic fields between moving mirrors: Singular waveforms inside Doppler cavities
Theodoros T. Koutserimpas, Constantinos Valagiannopoulos
Phenomena of wave propagation in dynamically varying structures have reemerged as the temporal variations of the medium's properties can extend the possibilities for electromagneti…
Generating Tokenizers with Flat Automata
Hans de Nivelle, Dina Muktubayeva
We introduce flat automata for automatic generation of tokenizers. Flat automata are a simple representation of standard finite automata. Using the flat representation, automata ca…
Exploring Supernova Gravitational Waves with Machine Learning
Ayan Mitra, Bekdaulet Shukirgaliyev, Y. Sultan Abylkairov +1
Core-collapse supernovae (CCSNe) emit powerful gravitational waves (GWs). Since GWs emitted by a source contain information about the source, observing GWs from CCSNe may allow us…
Distribution of a second-class particle's position in the two-species ASEP with a special initial configuration
Eunghyun Lee, Zhanibek Tokebayev
In this paper, we consider the two-species asymmetric simple exclusion process consisting of first-class particles and one second-class particle. We assume that the second-cl…
Improvement of the discrete Hardy inequality
Prasun Roychowdhury, Durvudkhan Suragan
We establish a novel improvement of the classical discrete Hardy inequality, which gives the discrete version of a recent (continuous) inequality of Frank, Laptev, and Weidl. Our a…
Constraining Scale Dependent Growth with Redshift Surveys
Mikhail Denissenya, Eric V. Linder
Ongoing and future redshift surveys have the capability to measure the growth rate of large scale structure at the percent level over a broad range of redshifts, tightly constraini…
Upon the horizon's verge: Thermal particle creation between and approaching horizons
Diego Fernández-Silvestre, Michael R. R. Good, Eric V. Linder
Quantum particle creation from spacetime horizons, or accelerating boundaries in the dynamical Casimir effect, can have an equilibrium, or thermal, distribution. Using an accelerat…
Fundamental length scale and the bending of light in a gravitational field
Philip Tee, Nosratollah Jafari
The canonical approach to quantizing quantum gravity is understood to suffer from pathological non-renomalizability. Nevertheless in the context of effective field theory, a viable…
Infrared acceleration radiation
Michael R. R. Good, Paul C. W. Davies
We present an exactly soluble electron trajectory that permits an analysis of the soft (deep infrared) radiation emitted, the existence of which has been experimentally observed du…

Alejandro J. Castro, Amin Esfahani, Lyailya Zhapsarbayeva
In this paper we establish the persistence property for solutions of the quartic generalized Korteweg-de Vries equation with initial data in weighted Sobolev spaces $H^{s}(\mathbb{…
A numerical study of stellar discs in galactic nuclei
Taras Panamarev, Bence Kocsis
We explore the dynamics of stellar discs in the close vicinity of a supermassive black hole (SMBH) by means of direct -body simulations. We show that an isolated nuclear stellar…
