Supernovae and Transients science with EUCLID, LSST, ZTF and ATLAS

My current main project is centred on supernovae and transients detection, follow-up for studies using data from the ESA space mission EUCLID. These data are complemented by public data provided by LSST, ZTF and ATLAS. One part of my research is focused on the detection of Magnified Supernovae in strong lensing systems (galaxy-galaxy or galaxy-galaxy cluster). The goal of this project is to get measurements of the Hubble Lemaitre constant, H0, in the local universe that are independent of the estimates obtained from the CMB analysis, or by using type Ia supernovae in the local universe. The other part of my research aim to understand the mechanisms leading to the formation of superluminous supernovae (SLSNe). 

At the IAC I'm working in close collaboration with Carlos Gutierrez on these subjects. I'm also involved in the SGLF (Supernova and Gravitational Lenses Follow-up) project led by Prof. Ismael Perez Fournon currently focused on supernovae and transients detections and studies using ZTF and LSST.

The SGLF project includes collaborations with the LensWatch project (P.I. Steve Rodney) and the SIRAH (Supernovae in the Infrared avec Hubble) project (P.I. Saurabh Jha).

In addition to these activities, from 2021 I'm leading a polarimetry observation program on a sample of Superluminous Supernovae (SLSNe) which main goal is to test the magnetar progenitor model. The project is using data from the GranTeCan (GTC), the Nordic Optical Telescope (NOT), the Liverpool Telescope (LT) and Las Cumbres Observatory (LCO).

Anomalous Microwave Emission in Molecular Clouds

Some of my research has been focused on the study on Anomalous Microwave Emission (AME) in a subsets of Galactic molecular clouds within the PolAME project and the RADIOFOREGROUNDS project. For this I use some data obtained with the Multi-Frequency Instrument (MFI) of the QUIJOTE-CMB experiment. 

With another group of collaborators from the IAC and from Japan we work on the development of the Cosmic Amorphous Dust (CAD) model which, in competition with other models, could also be a source of AME.

Magnetic Fields in Molecular Clouds and Star-Forming Regions

Some of my research has also been dedicated to the study of Magnetic Fields in Star-Forming regions. The role of this component in competition with the the turbulence of the Interstellar Medium (ISM) and gravity, which is the main contributor to star-formation in molecular clouds, is still not well understood (Planck and BLASTPol collaborations).

Observation Techniques

Photometry, spectroscopy and linear polarimetry in the visible, in the infra-red (IR), in the submillimetre (submm) and at radio-frequencies.
