Data-Driven Modelling to predict forest fire spread in the Patagonian region in Argentina
Lucas Becerra, Monica Malen Denham, Alejandro B. Kolton +1
Wildfires are among the most severe disturbances affecting forest ecosystems, with over 50,000 hectares burned in Patagonia, Argentina, during 2025 alone. This study implements a R…
Constraints on cyclotron features and accretion regime in the high-mass X-ray binary 4U 1700-37 from NuSTAR
Lautaro West-Ocampo, Federico A. Fogantini, Enzo A. Saavedra +6
4U 1700-37 is a wind-fed high-mass X-ray binary hosting a compact object, likely a neutron star, accreting from O6.5 Iaf+ supergiant HD 153919. Coherent pulsations not firmly detec…
Length-flexible strategies for efficient SERS performance in gold-nanorod-gapped nanoantennas
Sergio F. Flores-Correa, M. L. León Hilario, I. A. Ramos-Pérez +1
Surface-enhanced Raman spectroscopy (SERS) using gold-nanorod-dimer nanoantennas has shown great potential in various applications. This reflects in their large values of the custo…
A mean field analysis of the role of indirect transmission in emergent infection events
Tomás Ignacio González, María Fabiana Laguna, Guillermo Abramson
We developed a mathematical model to investigate the role of indirect transmission in the spread of infectious diseases, using the illustrative example of sarcoptic mange as a case…
Broad-emission-line dominated hydrogen-rich luminous supernovae
P. J. Pessi, J. P. Anderson, G. Folatelli +27
Hydrogen-rich Type II supernovae (SNe II) are the most frequently observed class of core-collapse SNe (CCSNe). However, most studies that analyse large samples of SNe II lack event…
Classification of Chandra X-ray Sources in Cygnus OB2
Vinay L. Kashyap, Mario G. Guarcello, Nicholas J. Wright +11
We have devised a predominantly Naive Bayes method to classify the optical/IR matches to X-ray sources detected by Chandra in the Cygnus OB2 association into foreground, member, an…
A blazar candidate for the Fermi source 4FGL J1848.7-0129
Pedro L. Luque-Escamilla, Josep Martí, Enrique Mestre +2
The Fermi source 4FGL J1848.7-0129 has been historically related to the globular cluster GLIMPSE-C01 since its very first detection. Although this association is widely accepted, a…
Angular Momentum Loss Rates in Be Stars Determined by the Viscous Decretion Disc Model
M. R. Ghoreyshi, C. E. Jones, A. Granada
Circumstellar discs around Be stars are formed by the material ejected by the central star. This process removes excess angular momentum from the star as viscosity facilitates the…
Supernovae double-peaked light curves from double-nickel distribution
Mariana Orellana, Melina Bersten
Among supernovae (SNe) of different luminosities, many double-peaked light curves (LCs) have been observed, representing a broad morphological variety. In this work, we investigate…
Simultaneous J-, H-, K- and L-band spectroscopic observations of galactic Be stars. I. IR atlas
Y. R. Cochetti, M. L. Arias, L. S. Cidale +2
It is already accepted that Be stars are surrounded by circumstellar envelopes, which are mostly compatible with a disc geometry in Keplerian rotation. We aim to obtain a more comp…
Smart: A program to automatically compute accelerations and variational equations
Daniel D. Carpintero, Nicolás P. Maffione, Facundo A. Gómez
Modern astronomical potentials modeling galaxies or stellar systems can be rather involved, and deriving their first derivatives (accelerations) and second derivatives (variational…
Type II supernovae from the Carnegie Supernova Project-I. III. Understanding SN II diversity through correlations between physical and observed properties
L. Martinez, J. P. Anderson, M. C. Bersten +17
SNe II show great photometric and spectroscopic diversity which is attributed to the varied physical characteristics of their progenitor and explosion properties. In this study, th…
Carnegie Supernova Project: kinky -band light-curves of Type Ia supernovae
P. J. Pessi, E. Y. Hsiao, G. Folatelli +19
We present detailed investigation of a specific -band light-curve feature in Type Ia supernovae (SNe Ia) using the rapid cadence and high signal-to-noise ratio light-curves obta…
Type II supernovae from the Carnegie Supernova Project-I. I. Bolometric light curves of 74 SNe II using uBgVriYJH photometry
L. Martinez, M. C. Bersten, J. P. Anderson +18
The present study is the first of a series of three papers where we characterise the type II supernovae (SNe~II) from the Carnegie Supernova Project-I to understand their diversity…
Type II supernovae from the Carnegie Supernova Project-I. II. Physical parameter distributions from hydrodynamical modelling
L. Martinez, M. C. Bersten, J. P. Anderson +18
Linking supernovae to their progenitors is a powerful method for furthering our understanding of the physical origin of their observed differences, while at the same time testing s…
Studying the interstellar medium to look for relics of triggered star formation among stellar clusters
S. Paron, A. Granada, M. B. Areal
Evidence of triggered star formation at large spatial scales involving stellar clusters is scarce. We investigate a Galactic region (l=130.0, b=0.35) populated by several open stel…
A Graph-based Similarity Function for CBDT: Acquiring and Using New Information
Federico E. Contiggiani, Fernando Delbianco, Fernando Tohmé
One of the consequences of persistent technological change is that it force individuals to make decisions under extreme uncertainty. This means that traditional decision-making fra…
The double-peaked type Ic Supernova 2019cad: another SN 2005bf-like object
C. P. Gutiérrez, M. C. Bersten, M. Orellana +23
We present the photometric and spectroscopic evolution of supernova (SN) 2019cad during the first days from explosion. Based on the light curve morphology, we find that S…
