The Success of Optical Variability in Uncovering AGNs in Low-stellar Mass Galaxies
S. Bernal, P. Sánchez-Sáez, P. Arévalo +3
We used random forest algorithms to classify all objects in a large portion of the sky, using optical light curves obtained, or built from images provided, by the Zwicky Transient…
Fermion masses and mixings and charged lepton flavor violation in a 3-3-1 model with inverse seesaw
A. E. Cárcamo Hernández, D. T. Huong, H. N. Long +1
We present a extension of the 3-3-1 gauge model supplemented by an flavor symmetry and cyclic discrete symmetries, including , , , , and .…
Host-star and exoplanet composition: Polluted white dwarf reveals depletion of moderately refractory elements in planetary material
Claudia Aguilera-Gómez, Laura K. Rogers, Amy Bonsor +6
Planets form from the same cloud of molecular gas and dust as their host stars. Confirming if planetary bodies acquire the same refractory element composition as their natal disc d…
The formation and stability of a cold disc made out of stellar winds in the Galactic Centre
Diego Calderón, Jorge Cuadra, Christopher M. P. Russell +3
The reported discovery of a cold (~10 K) disc-like structure within 0.005 pc around the super-massive black hole at the centre of the Milky Way, Sgr A*, has challenged our unde…
Deep kiloparsec view of the molecular gas in a massive star-forming galaxy at cosmic noon
Sebastián Arriagada-Neira, Rodrigo Herrera-Camus, Vicente Villanueva +10
We present deep ( 20 hr), high-angular resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations of the and transitions,…
The Hubble Tension: Relativistic Dark Matter Production from Long-lived Particles
Alvaro S. de Jesus, Matheus M. A. Paixão, Dêivid R. da Silva +2
The tension between direct measurements of the Hubble constant and those stemming from Cosmic Microwave Background probes has triggered a multitude of studies. The connection betwe…
Probing the rest-frame wavelength dependence of quasar variability : Insights from the Zwicky Transient Facility Survey
P. Patel, P. Lira, P. Arévalo +3
Context: Quasar variability can potentially unlock crucial insights into the accretion process. Understanding how this variability is influenced by wavelength is crucial for valida…
Phenomenology of an Extended Higgs Doublet Model with Family Symmetry
A. E. Cárcamo Hernández, Daniel Salinas-Arizmendi, Jonatan Vignatti +1
In order to explain the mass hierarchy and mixing pattern in the leptonic sector, we explore an extension of the Standard Model whose scalar sector includes one active and two iner…
The accreted Galaxy: An overview of TESS metal-poor accreted stars candidates
Danielle de Brito Silva, Paula Jofré, Clare Worley +2
The Milky Way is a mosaic of stars from different origins. In particular, metal-poor accreted star candidates offer a unique opportunity to better understand the accretion history…
Vector Dark Matter from the 5-Dimensional Representation of
Patricio Escalona, Sebastián Acevedo, Paulo Areyuna +3
The introduction of electroweak multiplets that transform under any representation of the standard gauge group suggests the existence of electrically neutral stable parti…
Results for pixel and strip centimeter-scale AC-LGAD sensors with a 120 GeV proton beam
Irene Dutta, Christopher Madrid, Ryan Heller +20
We present the results of an extensive evaluation of strip and pixel AC-LGAD sensors tested with a 120 GeV proton beam, focusing on the influence of design parameters on the sensor…
SDSS1335+0728: The awakening of a black hole
P. Sánchez-Sáez, L. Hernández-García, S. Bernal +22
The galaxy SDSS1335+0728, which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Fa…
The Pristine Inner Galaxy Survey (PIGS) X. Probing the early chemical evolution of the Sagittarius dwarf galaxy with carbon abundances
Federico Sestito, Anke Ardern-Arentsen, Sara Vitali +6
We aim to constrain the chemo-dynamical properties of the Sagittarius (Sgr) dwarf galaxy using carbon abundances. Our sample from the \textit{Pristine} Inner Galaxy Survey (PIGS) i…
A baseline on the relation between chemical patterns and birth stellar cluster
Theosamuele Signor, Paula Jofré, Luis Martí +1
The chemical composition of a star's atmosphere reflects the chemical composition of its birth environment. Therefore, it should be feasible to recognize stars born together that h…
Prediction of Energy Resolution in the JUNO Experiment
JUNO Collaboration, Angel Abusleme, Thomas Adam +645
This paper presents an energy resolution study of the JUNO experiment, incorporating the latest knowledge acquired during the detector construction phase. The determination of neut…
Early emission lines in SN 2024ggi revealed by high-resolution spectroscopy
Thallis Pessi, Régis Cartier, Emilio Hueichapan +6
We present an analysis of very early high-resolution spectroscopic observations of the Type II supernova (SN) 2024ggi, a nearby SN that occurred in the galaxy NGC 3621 at a distanc…
Flavor phenomenology of an extended 2HDM with inverse seesaw mechanism
N. T. Duy, D. T. Huong, A. E. Carcamo Hernandez
We perform a detailed and comprehensive study of several flavor physics observables in both lepton and quark sectors within the framework of an extended 2HDM theory where the inver…
A common framework for fermion mass hierarchy, leptogenesis and dark matter
