Rincón de la Ciencia

La Física de Partículas y la Radioactividad en el Rincón de la Ciencia del Mercado que se instala en el Campus San Francisco

El viernes 18 de marzo, el CAPA ha participado en el Rincón de la Ciencia del Mercado que se instala en el Campus San Francisco. Investigadores e investigadoras del CAPA han propuesto  pequeños juegos y demostraciones prácticas para conocer las partículas fundamentales, de las que está hecha toda la materia. También han ayudado a conocer la radioactividad que nos rodea.

Hands on particle physics- 18th international masterclass

La Facultad de Ciencias ha acogido, un año más,  la actividad “Hands on Particle Physics” organizada por el CAPA, y dirigida a estudiantes Bachillerato. Durante la mañana del jueves 17 de marzo, estudiantes de bachillerato se han introducido en el mundo de la física de partículas, y conocido el sistema de aceleradores y detectores utilizados en Física de Altas Energías. Por un día han sido científicos a la busca de la señal de la partícula Higgs en datos del experimento ATLAS del CERN. Por la tarde, han compartido sus resultados con estudiantes de institutos europeos de Polonia, república Checa, Alemania y Francia, en una teleconferencia organizada por el CERN.

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 .

Charla de Bodo Schwabe sobre «fuzzy dark matter» 🗓

Bodo Schwabe is a PostDoc Researcher at CAPA, focused on dark matter, axions and numerical simulations.

Abstract: On linear scales much larger than the typical extend of galaxies the standard model of cosmology with cold dark matter and a cosmological constant can reproduce observational data with high precision. But there are potential difficulties on galactic scales. In this 50 minutes master level lecture I will present the main concepts of fuzzy dark matter, a well motivated dark matter candidate that reproduces the successes of cold dark matter on large scales, while implying unique observable features like solitons and interference patterns within halos and filaments. During the lecture I will derive the equations of motion governing the evolution of fuzzy dark matter, concentrating on their physical implications. While conceptionally simply, solving these non-linear equations requires intensive numerical computations. Alongside the theoretical considerations I will therefore present numerical methods that have been used to analyse non-linear dynamics of fuzzy dark matter on (sub-)galactic scales

Hands on Dark Matter

¡Comienza la semana de la Materia Oscura!

Esta mañana estudiantes de bachillerato de los IES Clara Campoamor Rodríguez,  La AzucareraMiguel Servet, Andalán, Pedro de Luna e Itaca han participado en la actividad «Hands on Dark Matter» organizada por CAPA.  Han asistido a charlas, conectado con el Laboratorio subterráneo de Canfranc y el Centro de estudios de Física del Cosmos de Aragón (CEFCA), han detectado  radioactividad ambiental y  observado trazas de  rayos cósmicos en le laboratorio, comprobado la cantidad de materia oscura en una galaxia y el efecto de las lentes gravitacionales , y, finalmente, participado en un quiz, antes de la foto final. ¡Esperamos que hayan disfrutado, que hayan aprendido qué es la materia oscura y cómo la buscamos,   y que nos visiten de nuevo!
