Research field: Dark matter indirect searches. Computational cosmology. Small scale structure of the Universe

I completed my doctoral studies at the Institute for Theoretical Physics (UAM-CSIC) under the supervision of Prof. Dr. Miguel A. Sánchez-Conde. My dissertation, entitled "N-body cosmological simulations and gamma rays as tools to reveal the properties of dark matter halo substructure", was awarded the highest distinction, Sobresaliente Cum Laude, with the Extraordinary Doctoral Prize. Subsequently, I obtained a postdoctoral position at Durham University (UK) under the supervision of Prof. Dr. Carlos Frenk and Prof. Dr. Adrian Jenkins.

I have presented my work at over 25 national and international conferences, including a plenary talk at the International Cosmic Ray Conference held in Nagoya in the summer of 2023. I have taught computer science courses at both BSc and MSc level since 2019, and have co-supervised four Master's theses and one Bachelor's thesis. I have taken part in numerous outreach activities, often focusing on minority groups and bringing science to underserved communities.

Dr. Danielski obtained MSc and PhD at UCL (London, UK). She worked as a CNES Fellow at the Paris Observatory and Research Associate at the IAS and CEA (Paris, France). Following she moved to Spain where she was a Severo Ochoa Research Associate at the IAA (Granada). In 2023 she won the INAF astrophysics Fellowship at the Arcetry Observatory (Florence, Italy). 

Dr. Danielski merged for the first time the exoplanets and gravitational waves fields, opening a new window on the study of exoplanets, providing for the first time the possibility to probe for such a population everywhere in the Milky way and nearby galaxies. In 2020 she won an honourable mention by the Gravity Research Foundation. 

She is the scientific leader of the “Stellar Characterisation” WG of the Ariel Consortium, and the NASA point of contact  for the NASA Ariel Science Center, IPAC. Dr. Danielski is the scientific leader of the interdisciplinary team within the LISA Astrophysical WG, coordinating the development of the science case on planetary detection with GWs. 

RESEARCH INTERESTS: planetary systems characterisation and planetary systems long-term evolution, detection of exoplanets with gravitational waves, exoplanet atmospheres, stellar characterisation.

My name is Gaëtan Fichet de Clairfontaine, and I am a postdoctoral researcher in astrophysics at the University of Valencia, within the group of Manel Perucho. I obtained his PhD in Astrophysics in 2022 at the Observatory of Paris, with a focus on high-energy phenomena in relativistic jets and their interaction with the surrounding environment.

My research interests include active galactic nuclei (AGN), relativistic jet dynamics, jet-star interactions, non-thermal particle acceleration, and multi-messenger astrophysics, with particular emphasis on neutrino and high-energy emission. I combine relativistic magnetohydrodynamic simulations with radiative transfer and theoretical modeling to investigate observable signatures of jet dissipation processes.

In addition to my research activity, I am involved in some teaching duties. In the 2025-26 academic year, I was one of the instructors responsible for the outflows module in the course Astrofísica estel·lar (Group PT-T, course code 43296).

[Biography, english version]

I am a PhD student with a grant from the Ministry of Science, Innovation and Universities "Proyectos de Generación de Conocimiento". I work with cosmological simulations in the computational cosmology group of the astrophysics department of the University of Valencia. I graduated in physics at the Universidad Complutense and took the master's degree in theoretical physics at the Universidad Autónoma of Madrid. I also study philosophy at the Universidad Nacional de Educación a Distancia.

He obtained a Bachelor’s degree in Physical Sciences from the University of Valencia (2012) and a PhD in Physics cum laude from the University of Valencia (2018). He is currently a Ramón y Cajal researcher (since 2024) in the Department of Astronomy and Astrophysics. His research field is Numerical Relativity, which investigates the dynamics of physical systems described by General Relativity (GR) using numerical algorithms and computational resources to obtain their time evolution. In particular, he is interested in studying the dynamics of astrophysical compact objects (black holes and neutron stars), as well as more exotic theoretical compact objects (boson stars and scalarized black holes) and the gravitational-wave signals they emit.

Recently, he has been producing numerical gravitational waveforms from mergers of Proca stars (vector boson stars) to compare them with real gravitational-wave events detected by the LIGO–Virgo–KAGRA detector network, of which he has been a member since 2016. He is also interested in the formation of hairy black holes, either through the superradiant instability or via mergers of boson stars, as well as in extending the boson star family by considering multiple fields and assessing their stability.

He has participated in several research projects at the national, regional, and European levels.
