The THESAN project: Lyman-alpha emitters as probes of ionized bubble sizes
Meredith Neyer, Aaron Smith, Mark Vogelsberger +4
We use the THESAN radiation-hydrodynamics simulations to investigate how Lyman- emitters (LAEs) trace ionized bubble sizes during the Epoch of Reionization. We generate realisti…
Modeling of Electromagnetic Radiation using a Dual Four-Potential Representation: From Dipole Blade Radiators to Ribbon Loop-like Antennas
Robert Salazar, Camilo Bayona-Roa
In this paper, we explore classical electromagnetic radiation using a dual four-dimensional potential approach. Our focus is on the Planar Dipole Blade Antenna (PDBA), a syst…
Comparative Analysis of Molecular Dynamics and Method of Moments in Two-Dimensional Concentric Circular Layers
Robert Salazar, Cristian Cobos, Diego Jaramillo +1
In this manuscript, we undertake an examination of a classical plasma deployed on two finite co-planar surfaces: a circular region into an annular region with a…
Optimization of Antenna Performance for Global 21-cm Observations and Verification Using Scaled Copies
O. A. Restrepo, F. I. Lucero, G. Chaparro +5
The sky-averaged cosmological 21 cm signal can improve our understanding of the evolution of the early Universe from the Dark Age to the end of the Epoch of Reionization. Although…
Simulating the Detection of the Global 21 cm Signal with MIST for Different Models of the Soil and Beam Directivity
Raul A. Monsalve, Christian H. Bye, Jonathan L. Sievers +10
The Mapper of the IGM Spin Temperature (MIST) is a new ground-based, single-antenna, radio experiment attempting to detect the global 21 cm signal from the Dark Ages and Cosmic Daw…
Mapper of the IGM spin temperature: instrument overview
R. A. Monsalve, C. Altamirano, V. Bidula +17
The observation of the global 21 cm signal produced by neutral hydrogen gas in the intergalactic medium (IGM) during the Dark Ages, Cosmic Dawn, and Epoch of Reionization requires…
The Early Data Release of the Dark Energy Spectroscopic Instrument
DESI Collaboration, A. G. Adame, J. Aguilar +266
The Dark Energy Spectroscopic Instrument (DESI) completed its five-month Survey Validation in May 2021. Spectra of stellar and extragalactic targets from Survey Validation constitu…
Constraining cosmological parameters from N-body simulations with Variational Bayesian Neural Networks
Héctor J. Hortúa, Luz Ángela García, Leonardo Castañeda C
Methods based on Deep Learning have recently been applied on astrophysical parameter recovery thanks to their ability to capture information from complex data. One of these methods…
Expansion Formula For the Magnetic Field of a Periodically Deformed Circular Current Loop
Robert Salazar, Gabriel Téllez, Camilo Bayona-Roa
A method is derived to obtain an expansion formula for the magnetic field generated by a closed planar wire carrying a steady electric current. The…
Electric Vector Potential Approach in Electrostatics: The Surface Electrode
Robert Salazar, Camilo Bayona-Roa, Gabriel Téllez
Electric vector potential is a legitimate but rarely used tool to calculate the steady electric field in free-charge regions. Commonly, it is preferred to emplo…
Electrostatic Field of Angular-Dependent Surface Electrodes
Robert Salazar, Camilo Bayona-Roa, J. S. Solís-Chaves
We present an analytic strategy to find the electric field generated by surface electrode SE with angular dependent potential. This system is a planar region kept at…
Photoproduction of pentaquarks states at the LHC
V. P. Goncalves, M. M. Jaime
In this paper we investigate the production of pentaquark states in the photon -- proton interactions present in hadronic collisions at the RHIC and LHC. We consider two phenomenol…
Transitional disk archeology from exoplanet population synthesis
Germán Chaparro Molano, Frank Bautista, Yamila Miguel
Increasingly better observations of resolved protoplanetary disks show a wide range of conditions in which planets can be formed. Many transitional disks show gaps in their radial…
The radius inflation problem in short-period low-mass binaries: a large sample analysis
Hernan E. Garrido, Patricia Cruz, Marcos P. Diaz +1
Due to the recent increase in the availability of photometric time-series databases, the characterisation of low-mass eclipsing binaries for the study of their orbital and physical…
The CGM and IGM at z5: metal budget and physical connection
Alex Codoreanu, Emma V. Ryan-Weber, Luz Ángela García +5
We present further results of a survey for absorption line systems in the spectra of four high redshift quasars (5.79 z 6.13) obtained with the ESO Very…
Predicting extragalactic distance errors using Bayesian inference in multi-measurement catalogs
Germán Chaparro Molano, Juan Carlos Cuervo, Oscar Alberto Restrepo Gaitán +1
We propose the use of robust, Bayesian methods for estimating extragalactic distance errors in multi-measurement catalogs. We seek to improve upon the more commonly used frequentis…
Low Dimensional Embedding of Climate Data for Radio Astronomical Site Testing in the Colombian Andes
Germán Chaparro Molano, Oscar Leonardo Ramírez Suárez, Oscar Restrepo +1
We set out to evaluate the potential of the Colombian Andes for millimeter-wave astronomical observations. Previous studies for astronomical site testing in this region have sugges…
