The dark Universe studied from deep underground: Exploring the low-mass frontier

LIP, Instituto para a Investigação Interdisciplinar da ULisboa

Dark matter remains one of the puzzling unsolved mysteries of the Universe. While its existence today is supported by a variety of observations on all cosmological scales, its nature remains in the dark. Direct dark matter searches investigate this question by directly observing interactions of dark matter particles with ordinary matter in earth-bound detectors. most commonly dark matter particles elastically scattering off nuclei.

Among the numerous experiments around the globe, CRESST is one of the pioneers, located since 1996 at the Laboratori Nazionali del Gran Sasso in Italy. Its target are scintillating CaWO4 crystals, which are operated as cryogenic calorimeters at millikelvin temperatures. For each interaction CRESST records a phonon and a scintillation light signal, the former precisely measuring the energy deposited in the crystal and the latter providing particle identification on an event-by-event basis. Cryogenic calorimeters are particularly suited to measure even very tiny energy depositions (<1keV) which makes the CRESST experiment leading the field for light dark matter particles (with masses below 1.7GeV/c2), extending for the first time the reach of a direct search to the sub-GeV/c2 mass regime. For CRESST-III, whose Phase 1 started data taking in August 2016, detectors have been optimized to reach the performance required to further probe the low-mass region with unprecedented sensitivity. In this contribution the achievements of the CRESST-III detectors will be thoroughly discussed together with preliminary results and perspectives of Phase 1.

Overview: Currently, climate changes or alterations are known to be reflected on the stable isotope ratios of Hydrogen, Nitrogen, Carbon, Oxygen and Sulphur present in atmospheric gas forms, fresh or ocean water, as well as in plants and animals and organi

Objectives: Evolutionary theory provides a framework for understanding all living systems.

Objectives: To introduce participants to the details of communicating science to non-specialized audiences, including, but not exclusive to, public and private stakeholders, students and teachers, and media professionals.

Objectives: Natural history museums are privileged spaces for seminal research on different subjects of biological sciences such as biodiversity, evolution, ecology, biogeography and taxonomy.

Objectives: Provide students with basic workflows, platforms and tools to increase reproducibility at all scientific levels.

Objectives: Under the general framework of Global Change Ecology, the goal of this course is to provide the participants with the most recent and practical knowledge on the use of Functional Diversity.

Objectives: The objective of this course is to introduce participants to the details of communication and writing scientific publications. The main emphasis is on the most common form, the “primary scientific paper”, but other forms will be covered.

Objectives: Lack of fertile land to feed the exponentially growing population, insufficient water availability and quality, changes in the flow of nutrients through the bio-geo-cycles (especially N and P) and climate and land use changes are impacting ecosystem

Objectives: Symbiosis is a key strategy for life on Earth.

Objectives: The goal of this course is to provide to the participants with current and practical knowledge on urban ecology, including ecological and social aspects. It aims at providing an integrated approach on urban socio-ecological systems.

Objectives: Citizen science can be part of the larger process of engaging people in new forms of interaction in scientific research, challenging scientists and citizens whilst enlarging scientific knowledge and providing learning opportunities for all part

Objectives: This course aims at: 1) exploring how scientists can use social media as tools to enhance the communication of their research and the dialogue with society, and 2) discussing the differences that exist in the work of scientists and journalists

Objectives: This course will teach how to apply the SWAT eco-hydrological model to assess the impacts of climate and associated changes on water-soil-plant interactions, and consequences to water resources, soil erosion and nutrient cycles.

Objectives: Provide students with basic knowledge of R programming, allowing them to manipulate and visualize data with R.
