El comité organizador comunicará la aceptación de las presentaciones orales seleccionadas el 18 de noviembre de 2022. El día 25 de noviembre de 2022 se cerrarán las inscripciones.

TREXDM: working in the LSC clean room

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

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

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

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.

Feebly Interacting Sectors Impact on Cosmology & Astrophysics.

Virtual workshop (1st-4th March 2022)

Different types of astrophysical environments—such as horizontal branch stars, the sun, supernovae (SNe), neutron stars, black holes—offer different guises to explore fundamental physics, and in particular feebly interacting sectors.

A collaborative effort between particle physicists, astrophysicists and astronomers is highly desirable. This interaction can help refine existing ideas, identify the most promising candidate theories and come up with new possible signatures from astrophysical objects.

The goal of this workshop is to bring together the relevant communities, paving the way for a new decade in fundamental physics.

Charla de Miguel Ángel Sánchez Conde sobre detección indirecta de Materia Oscura

Indirect Dark Matter

Dr. Miguel Ángel Sánchez Conde is a researcher at Universidad Autónoma de Madrid leading a group with a focus on gamma-ray dark matter searches, astroparticle physics and cosmological simulations.

Abstract: The nature of the dark matter (DM) in the Universe is one of the greatest mysteries of our time, and its quest of utmost relevance for the whole scientific community. Among the efforts currently ongoing, the search for annihilation or decay products of DM particle candidates like the WIMP already provided abundant information and allowed to set competitive constraints on the DM particle properties. In this review talk, I will summarize the current status of this ‘indirect’ search of DM, paying particular attention to results obtained with gamma-ray telescopes from the direction of the best astrophysical targets. I will finally discuss on future DM sensitivity prospects and new DM search opportunities.»

Horario: 12:00, del jueves 9 de diciembre, en el seminario de Física nuclear u on-line .
