Un nou veí: El descobriment del Planeta Barnard B
Barcelona, Cosmocaixa
Avui dia coneixem gairebé 4.000 planetes que orbiten al voltant d'altres estrelles, i l'astrofísica ens ha revelat una riquesa de sistemes planetaris molt superior a la que ens imaginàvem. La majoria d'aquests planetes són difícils d'estudiar en detall perquè orbiten al voltant d'estrelles llunyanes i poc brillants. Però si els planetes es troben al voltant d'astres propers en podem obtenir molta més informació, i fins i tot somiar poder-los veure directament algun dia.

ICCUB CONFERENCE: Ten years with Timepix
Aula Fontserè
Engaging school children with cutting edge physics and technology has led to the development of a school research institute where students contribute in space science, particle physics and now across the sciences.

ICCUB SEMINAR: Measurements of Degree-Scale B-mode Polarization with the BICEP/Keck Experiments at South Pole
DAM Seminar
The BICEP and Keck experiments, located at the South Pole, are currently observing the polarized microwave sky at the degree scale using refractive telescopes. They are searching for a signature of primordial gravitational waves in the so-called B modes of the cosmic microwave background (CMB), parametrized with the tensor-to-scalar ratio r.

ICCUB SEMINAR: Formation and evolution of GCs in a cosmological context: the E-MOSAICS project
DAM Seminar
By Marta Reina Campos (Heidelberg University). Globular clusters (GCs) are massive (mostly M>1e5 Msun), metal-poor (mostly sub-solar) and old (mostly > 10 Gyr) stellar clusters that have remained gravitationally bound till the present day.

Third Barcelona Technoweek – Course on Semiconductor Detectors
Barcelona, Institute of Cosmos Sciences
Barcelona Techno weeks are a series of meeting point events around a technological topic of interest for both academia and industry. They include comprehensive multidisciplinary keynote presentations by world experts that are combined with networking activities to foster collaboration among participants.

ICCUB SEMINAR – Gaia as gravitational wave detector
DAM Seminar
ESA's second space astrometry mission Gaia started its scientific operations in July 2014. During its routine science operation Gaia is delivering an immense dataset of high-accuracy positional observations which already led to two Data Releases containing high-accuracy position, parallaxes and proper motions of over a billion sources.

ICCUB SEMINAR – The Imaging X-ray Polarimetry Explorer (IXPE)
DAM Seminar Room (724), 7th floor
IXPE, the Imaging X-ray Polarimetry Explorer, has been selected by NASA as the next mission in the Small Explorer Program, for a launch in early 2021. IXPE, a collaboration between NASA and ASI (the Italian Space Agency), will reopen, after a gap of more than 40 years, the X-ray polarimetric observing window.

ICCUB SEMINAR – Active galactic nuclei as cosmological probes
DAM Seminar Room (724), 7th floor
I will present the latest results on our analysis of the non-linear X-ray to UV relation in a sample of optically selected quasars from the Sloan Digital Sky Survey, cross-matched with the most recent XMM-Newton and Chandra catalogues. I will show that this correlation is not only very tight, but can be potentially even tighter by including a further dependence on the emission line full-width half maximum.

ICCUB SEMINAR – QCD Axion Searches with Microwave Filters
Aula 507 (Pere Pascual)
We have proposed, designed and constructed a variant of the conventional axion haloscope concept that could be competitive in the search for dark matter axions of masses in the decade 10-100 μeV. Our haloscope consists of an array of small microwave cavities connected by rectangular irises, in an arrangement commonly used in radio-frequency filters.

ICCUB COURSE – Astrophysical Black Holes
DAM Seminar Room (724), 7th floor
The course will provide fundamental notions about astrophysical black holes: the evidence for their existence, the behaviour of matter around them, the classes of sources in which they reside, the techniques to measure their basic properties, and in particular their angular momentum.

ICCUB SEMINAR – LIGO/Virgo and the quest for gravitational waves
DAM Seminar Room (724), 7th floor
The Nobel-Prize-winning observations of gravitational waves by the Advanced LIGO and Advanced Virgo detectors have opened an entirely new window to study the universe. The detection of the first gravitational-wave signal, GW150914, is one of the greatest scientific milestones of all time, confirming a century-old prediction of Albert Einstein’s Theory of General Relativity.

ICCUB SEMINAR – Connecting Type Ia supernovae with the metallicity of their progenitors
DAM seminar room (724), 7th floor
Thermonuclear explosions of carbon-oxygen white dwarfs (CO WDs), or Type Ia supernovae (SNIa) are important tools for cosmology. SNIa observations show the recent acceleration and previous deceleration of the expansion rate of the Universe, in agreement with a 70% of the energy-matter content of the Universe in form of dark energy.

ICCUB SEMINAR – Finding the double sunsets: close binary stars, large spectroscopic surveys
DAM seminar room (724), 7th floor
I will discuss our present knowledge of the statistics of stellar multiplicity (the multiplicity fraction and the distribution of periods, mass ratios, and eccentricities), and the implications for stellar evolution, in particular for Type Ia Supernovae (SN Ia).

ICCUB SEMINAR – Trusting Theory in Cosmological Tests of Gravity
DAM seminar room (724), 7th floor
Modifications to gravity can provide attractive alternatives to the dark components of the standard model of cosmology. These modifications to general relativity (GR) must be hidden at small scales where theory is well tested, and so one naturally looks to the large scales in order to detect any deviations from GR.
