Elliptic reconstruction and a posteriori error estimates for fully discrete linear parabolic problems
Omar Lakkis, Charalambos Makridakis
We derive aposteriori error estimates for fully discrete approximations to solutions of linear parabolic equations on the space-time domain. The space discretization uses finite el…
Overdensity of Lyman-Break Galaxy Candidates Around Hot Dust-Obscured Galaxies
Dejene Zewdie, Roberto J. Assef, Trystan Lambert +15
Hot dust-obscured galaxies (Hot DOGs), are a family of hyper-luminous, heavily obscured quasars. A number of studies have shown that these objects reside in significantly overdense…
Moduli spaces and breather dynamics of analytic solutions in Heisenberg exchange-free chiral magnets
Bruno Barton-Singer, Stefano Bolognesi, Sven Bjarke Gudnason +1
We investigate the special case of the chiral magnet with vanishing Heisenberg exchange energy, whose axisymmetric Skyrmion solution has previously been found. The dynamical equati…
First-principles derived force field for h-BN monolayer nanostructures: Applications to sheets, nanotubes and nanotori
Aristotelis P. Sgouros, Markos Arapchatzis, Nektarios N. Lathiotakis +2
In this work, we present an empirical force field for hexagonal boron nitride (hBN) monolayers, derived via a bottom-up strategy from first principles calculations. We aim to deliv…
Searching for a signature of turnaround in galaxy clusters with convolutional neural networks
Nikolaos Triantafyllou, Giorgos Korkidis, Vasiliki Pavlidou +1
Galaxy clusters are important cosmological probes that have helped to establish the CDM paradigm as the standard model of cosmology. However, recent tensions between diff…
The WALOP-North Instrument I: Optical Design, Filter Design, Calibration
John A. Kypriotakis, Siddharth Maharana, Ramya M. Anche +18
The Wide Area Linear Optical Polarimeter North (WALOP-North) is an optical polarimeter designed for the needs of the PASIPHAE survey. It will be installed on the 1.3m telescope at…
Highly-stable, eco-friendly and selective Cs2AgBiBr6 perovskite-based ozone sensor
Aikaterini Argyrou, Rafaela Maria Giappa, Emmanouil Gagaoudakis +5
Lead halide perovskites have attracted considerable attention as potential gas sensing elements due to their unique ability to detect and respond to an external stimulus with measu…
Molecular gas stratification and disturbed kinematics in the Seyfert galaxy MCG-05-23-16 revealed by JWST and ALMA
D. Esparza-Arredondo, C. Ramos Almeida, A. Audibert +30
Understanding the processes that drive the morphology and kinematics of molecular gas in galaxies is crucial for comprehending star formation and, ultimately, galaxy evolution. Usi…
Spectroscopic Modeling of Luminous Transients Powered by H-Rich and He-Rich Circumstellar Interaction
Gururaj A. Wagle, Emmanouil Chatzopoulos, Michael J. Baer
In this study, we perform detailed spectroscopic modeling to analyze the interaction of circumstellar material (CSM) with ejecta in both hydrogen-rich and hydrogen-poor superlumino…
The ALMA-CRISTAL Survey: Complex kinematics of the galaxies at the end of the Reionization Era
K. Telikova, J. González-López, M. Aravena +18
The history of gas assembly in early galaxies is reflected in their complex kinematics. While a considerable fraction of galaxies at z~5 are consistent with rotating disks, current…
Multi-wavelength study of OT 081: broadband modelling of a transitional blazar
MAGIC Collaboration, H. Abe, S. Abe +270
OT 081 is a well-known, luminous blazar that is remarkably variable in many energy bands. We present the first broadband study of the source which includes very-high-energy (VHE, $…
Wettability and Color Change of Copper by Controlling Area Fraction of Laser Ablated Surface
Mantas Gaidys, Stella Maragkaki, Alexandros Mimidis +6
In this research, wettability control by area fraction of laser ablated surface of copper is presented. The functional surfaces with full wettability control from highly hydrophili…
A wiggling filamentary jet at the origin of the blazar multi-wavelength behaviour
C. M. Raiteri, M. Villata, M. I. Carnerero +96
Blazars are beamed active galactic nuclei known for their strong multi-wavelength variability on timescales from years down to minutes. We aim to investigate the suitability of the…
