Studies of early galaxy formation are crucial for understanding the processes that have shaped the current Universe. Galaxies with intense star formation at z $>$ 6 are key to events such as reionization, but their faintness limits detailed studies. At lower redshifts (z $\sim$ 1), analogous galaxies allow for better characterization. Extreme Emission Line Galaxies (EELGs) stand out due to...

The study of the first galaxies which contributed to the ionization of the universe will become possible with an integral field and multi-object spectrograph like MOSAIC (significant contribution from GUAIX), set to be installed on the 39m Extremely Large Telescope (ELT), currently under construction. As a pilot study for that, a detailed two-dimensional study of the physical properties of a...

In this talk, I will present the main scientific outcomes of my PhD thesis, which focuses on the analysis of dwarf satellite galaxies in cosmological zoom-in simulations of Milky Way–mass halos. First, I will briefly summarize the core results regarding the physical mechanisms that drive the quenching of star formation in satellite galaxies as they interact with their host halos, within the...

Las galaxias ultradifusas (UDGs) son un caso extremo de galaxias de bajo brillo superficial, muy extendidas ($R_{e} \geq 1.5$ kpc) y con luminosidades en el régimen de enanas. Aunque son un grupo abundante en numerosos cúmulos, su naturaleza y los mecanismos responsables de su formación siguen siendo una cuestión abierta. El análisis de su posición en el plano tamaño-luminosidad constituye una...

The formation pathways of Compact Stellar Systems (CSSs) remain poorly understood. Some CSSs exhibit signatures of past interactions and mergers, in which tidal stripping is thought to play a key role. These systems often host dynamical structures typically associated with more massive galaxies, such as supermassive black holes (SMBHs), nuclear thin disks, and are preferentially located in...

El objetivo de mi tesis es estudiar los perfiles de masa de cúmulos de galaxias utilizando el método cáustico como una preparación cientÍfica del próximo survey CATARSIS. Durante la tesis estudiamos las limitaciones del método así como las propiedades dinámicas de los cúmulos de galaxias: subestructuras, anisotropía y formas complejas de triaxialidad propias de la formación de estas grandes...

This talks presents a general analysis of the Star Formation Main Sequence, exploring its connection with stellar [Mg/Fe] abundances. Global trends linking star formation activity with the chemical evolution of galaxies are examined. The results provide a generic framework for understanding the physical processes regulating both properties.

La ética en la ciencia no se limita no se limita a los campos de la biología o la medicina, pero ¿somos conscientes de ello?

Esta charla pretende ser una reflexión sobre la capacidad crítica de los investigadores para no caer en el sesgo de confirmación y para ser conscientes de la necesidad de cuestionarnos si en nuestro trabajo diario nos documentamos suficientemente y evaluamos todas las... -

Numerical Simulations of the Universe provide a unique laboratory for studying the assembly LSB features around galaxies. Until recently, the resolution of these simulations only allowed to resolve the coarsest LSB structures, but the arrival of Very-High resolution simulations it is becoming possible to resolve stellar stream around massive hosts.
On this talk, we will present preliminary...

La charla tratará sobre mi tesis en clasificación y caracterización de enanas en la misión ARRAKIHS. Se comenta el problema de la función de masa de subhalos y cómo aparece en relación ARRAKIHS para tratar, en general, el universo de bajo brillo superficial. Desde ahí, se centra la charla en cómo se tratan las imágenes simuladas de tipo-ARRAKIHS para generar (con GNUAstro) catálogos...

Outflows play a central role in AGN feedback, transporting mass and energy from the nucleus into the host galaxy on a wide range of spatial scales. Theoretical models predict that sub-relativistic Ultra Fast Outflows (UFOs), once they collide with the surrounding interstellar medium (ISM), decelerate and decrease in ionization state, potentially giving rise to large-scale, multi-phase outflows...

In this talk, I will introduce the AC3 project (Agile and Cognitive Cloud-edge Continuum Management, https://ac3-project.eu/), a European-funded initiative under Horizon Europe. AC3’s goal is to build a smart management system that works across the full cloud-edge continuum, from centralized data centers to far-edge devices. The project includes three different Use Cases that together serve as...

Galactic winds, often driven by intense star formation or AGN activity, are particularly significant in the context of galactic feedback, being active agents of the baryonic cycle of the galaxy, mainly by redistributing gas, dust, and metals both within the galaxy and in the intergalactic medium (IGM). These winds may also influence the star formation of their host galaxies, acting either as a...

I study the early evolution of star-forming regions and stellar clusters in the nearby galaxy NGC 1433 using JWST Paschen-α imaging combined with HST, PHANGS-MUSE, and cluster catalogs. I constructed a homogeneous Paα source catalog and matched each region to nebular Hα emission and young stellar clusters. Using physically calibrated PHANGS Hα fluxes, I derived reliable Paα/Hα ratios to...

We have started a pilot project to study the spatially resolved Sunyaev-Zeldovich signal in a few clusters of galaxies. This work is in preparation for the CATARSIS survey that the TARSIS instrument will carry out at the CAHA 3.5m telescope after installation and commissioning. I will describe the work done so far on this pilot and the motivation to expand it though a future AtLAST-CATARSIS program.

factor (αCO) and dust-to-gas ratio (DGR) for NGC4214, NGC2976,
NGC3077, NGC2403 and NGC0925. We have simultaneously solved for αCO
and the DGR by assuming that the DGR is approximately constant on
kiloparsec scales. With this assumption, we can combine maps of dust
mass surface density, CO-integrated intensity, and HI...
