Pablo Renard joins ICE-CSIC as the Calibration Scientist of the ARRAKIHS mission, which will observe close spiral galaxies to unprecedented low surface brightness, revealing the extremely faint structures in their outskirts. His main job is making sure that we understand the instrument well enough to reach the very demanding detection limits of ARRAKIHS. His research interests also include studying large-scale structure with the Lyman-alpha line, and observing the expansion of the Universe with cosmic chronometers, among others.

Yerong Xu is the junior postdoctoral fellow at ICE-CSIC. His research interests focus on active galactic nuclei (AGN), powered by accretion onto supermassive black holes (SMBHs). Using the X-Ray Imaging and Spectroscopy Mission (XRISM) and other X-ray space telescopes (i.e. XMM-Newton, Chandra, Swift and NuSTAR), Yerong studies the circumnuclear environment of SMBHs and the role of AGN outflows in the BH-galaxy co-evolution.

Alba Moras Martínez has recently started her PhD in the Advanced Engineering Unit as part of the LISA project. Her research focuses on enhancing temperature sensitivity using a Whispering Gallery Mode Resonator (WGMR) as a sensor. Additionally, she contributes to the development of high-precision laser frequency stabilization techniques in the low-frequency regime. To achieve these goals, they analyze the dynamic interactions between different polarized modes resonating within the WGMR.

Maria Edvige Ravasio is a La Caixa Junior Leader Fellow who recently joined our Institute. Maria’s project aims to understand some of the most extreme environments in our universe, namely powerful outflows of matter and energy launched in the form of jets at the end of the lives of some stars. To do so, she will investigate gamma-ray bursts (GRBs), highly variable and energetic outbursts from these relativistic jets. Maria will use X-ray observations from the recently launched Einstein Probe and other high-energy satellites to study the properties of these events, formerly discovered only in gamma-rays, and what they can tell us about the progenitor systems and the physics of jets.
