TREXDM: working in the LSC clean room

gloriaby gloria

We share the work done in a clean room to make changes inside a detector. As you can see, taking care of possible contamination is essential and, for this reason, the clean room of the Canfranc Underground Laboratory is used. The team has been working all last week and continue to work this week to get the detector ready to take data the next week. In addition to this work, they have made this fantastic video and added music. Bravo!!
TREXDM is an experiment devoted to the search for low-mass WIMPS, installed at the LSC.

«CosmicWISPers» COST Action approved

igorby igor

A new COST Action called «COSMIC WISPers in the Dark Universe: Theory, astrophysics and experiments» has been recently approved by the COST Committee. The Action deals with axions and other WISPs and their connection with astrophysics and cosmology. It is coordinated by A. Mirizzi of U. Bari and counts withe the participation of CAPA members, and many of the axion leading researchers in Europe and elsewhere.

Good news for the axion community!

Call for research position at the Nuclear and Astroparticle Physics Group

gloriaby gloria

Call for research position at the Nuclear and Astroparticle Physics Group – Centro de Astropartículas y Física de Altas Energías (CAPA)- Universidad de Zaragoza
1 postdoc position
We are looking excellent and motivated candidates with experimental particle physics background to join the IAXO-UZ group.
The host group at the University of Zaragoza has a leading role in the International Axion Observatory (IAXO) experiment, whose primary aim is the detection of axions emitted by the Sun.
The near-term goal of the collaboration is the construction and operation of BabyIAXO, an intermediate stage to serve as prototype of the final IAXO systems, but already with a relevant physics program in itself.
The five years duration of the project should encompass the construction, commissioning and first physics results of BabyIAXO.
The positions here offered are intended to reinforce the activities of the Zaragoza group for the preparation of the BabyIAXO experiment, which are focused in the development, preparation and characterization of a new low-background Micromegas-based x-ray detector for the focal point of BabyIAXO.

Interested candidates should send their CV, a letter of motivation to:
iaxorecruitment@unizar.es.
In addition, they should arrange for two letters of recommendation to be send to the same address.

More details on the research performed in our group can be found here:

Charla de Jacobo Varela: «Synergies in plasma physics: exoplanet habitability and radio emission» 🗓

Charla

Lecturer:  Jacobo Varela Rodríguez (Universidad Carlos III, Madrid)

Abstract: This presentation discusses synergies between different plasma physics fields, emphasising in the astrophysical plasmas. In particular, exoplanet habitability is a hot topic in the scientific community, devoted to developing new observational as well as numerical models dedicated to analyzing the exoplanet environment. In the last decade, MHD models are applied to study the magnetic field generation by dynamo effect in the convective layer of stars, the production of stellar winds as well as the interaction of the stellar wind with planetary magnetospheres. We show the last advances in the modelling efforts to analysis the effect of the space weather conditions on the exoplanet habitability, that is to say the interaction of the stellar wind and the exoplanet magnetosphere. In addition, the radio emission from exoplanet magnetospheres is numerically evaluated identifying trends regarding the space weather properties

Charla de Carlos López Sanjuan: La evolución espectral de enanas blancas con J-PLUS

gloriaby gloria

J-PLUS

Dr. Carlos López Sanjuan is a researcher at CEFCA (Centro de Estudios de Física del Cosmos de Aragón).

Abstract: White dwarfs are the degenerate compact remnants of stars with masses below 8 Msun. They do not have an internal source of energy and just cool down with time. In addition, they show a diversity of atmospheric compositions in their spectra, with sources presenting hydrogen (H) lines (DA type), helium (He) lines (DO and DB type), metal lines (DZ type), and featureless spectra (DC type) among others. In this seminar we present our recent work about the spectral evolution of white dwarfs with effective temperature (i.e., their age) using the Javalambre Photometric Local Universe Survey (J-PLUS). We analysed 5926 white dwarfs with r <= 19.5 mag in common between the white dwarf catalogue presented in Gentile Fusillo et al. 2021, defined from Gaia EDR3, and J-PLUS DR2. We estimated their effective temperature (Teff), surface gravity, parallax, and spectral type; and the probability of having a H-dominated atmosphere (p_H) for each source. Our analysis yields a 21 +- 3% increase in the fraction of He-dominated white dwarfs from Teff = 20000 K to  Teff = 5000 K.

Horario: 12:00, del jueves 10 de marzo, en el seminario de Física Nuclear. On-line
