Observaci\'on de lentes gravitatorias con ALMA

TL;DR

This paper aims to select gravitational lens candidates from the CASTLES database for observation with ALMA, to improve existing models of these systems through submillimeter data and modeling with GravLens software.

Contribution

It introduces a method for selecting promising quadruple-image gravitational lens systems for ALMA observations to enhance model accuracy.

Findings

Selected 12 promising quadruple lens systems from CASTLES.

Plan to observe these systems with ALMA for extended source detection.

Intends to improve gravitational lens models with new submillimeter data.

Abstract

Gravitational lensing is a fundamental tool for cosmology. A recent instrument which will provide more information for models of these objects is ALMA. Our goal is to select lens candidates to observe with ALMA and then model them using GravLens Software. We had selected 12 quadruple images systems from the CASTLES database, which show a high probability of observing extended sources in the submillimetric range. These new data will allow us to improve existing models. Las lentes gravitatorias son una herramienta fundamental para la cosmolog\'ia. Un nuevo instrumento que nos proporcionar\'a mayor informaci\'on para los modelos de estos objetos, es ALMA. Nuestro objetivo es seleccionar lentes candidatas para observar con ALMA y posteriormente modelarlas mediante el programa GravLens. Seleccionamos de la base de datos de CASTLES, 12 sistemas cu\'adruples, los cuales tienen mayor probabilidad de observar fuentes extendidas en el rango submilim\'etrico. Estos nuevos datos nos permitir\'an mejorar los modelos exitentes para dichos sistemas.
