Mysteriously in-sync pulsar challenges existing theories
Researchers from the Institute of Space Studies of Catalonia (IEEC) at the Institute of Space Sciences (ICE, CSIC) have contributed to a research study that, for the first time, detected synchronised pulses of optical and X-ray radiation from a mysterious pulsar. The observations indicate that a new physical mechanism might be needed to explain the behaviour of fast-spinning sources like this one, known as transitional millisecond pulsars.
Planetary Trio with Possibly Habitable World
The CARMENES spectrograph in Calar Alto, Spain, has contributed measurements to a study of exoplanets around GJ 357, a star that lies 31 light years away from us and is about one third the size of the Sun. A planet discovered by NASA’s Transiting Exoplanet Survey Satellite (TESS) around this star triggered new observations and a careful revision of all the data existing on the star.
IEEC releases anniversary image of the Moon in celebration of 50 years since humankind set foot on a celestial body
On 20 July 1969, at approximately 20:17:40 UTC, the Apollo Lunar Module Eagle landed at the site called Tranquility Base, in the south-western corner of the lunar lava-plain called Mare Tranquillitatis ("Sea of Tranquility"). The landing area where the intrepid space explorers set their foot for the first time in history, is marked in this image taken with the Joan Oró Telescope (TJO) from the Montsec Observatory (Observatori Astronòmic del Montsec, OAdM).
CARMENES finds two temperate Earth-mass planets around a nearby small star
Researchers from the Institute of Space Studies of Catalonia (IEEC — Institut d’Estudis Espacials de Catalunya) have participated in an international study carried out by the CARMENES consortium, which has discovered two small, terrestrial planets around Teegarden’s Star. The planets have masses similar to Earth and their temperatures could be mild enough to sustain liquid water on their surfaces. Observations were carried out with the CARMENES instrument in Calar Alto (Spain), as well as several other smaller complementary facilities, including IEEC’s Telescopi Joan Oró, at the Montsec Astronomical Observatory. The scientific paper is led by researchers at the University of Göttingen and appears in Astronomy & Astrophysics.
The analysis of a meteorite reveals secrets about the birth of the Solar System
Research led by the University of Arizona in collaboration with IEEC-UPC has led to the discovery of a meteorite grain forged during the final phases of a star that disappeared a long time ago.
Observing the interstellar comet C/2019 Q4 with the Joan Oró Telescope of the Montsec Astronomical Observatory
In September 2019, the Joan Oró Telescope (TJO) of the Montsec Astronomical Observatory (Observatori Astronòmic del Montsec, OAdM) is observing the interstellar comet C/ 2019 Q4 (Borisov), more popularly known as “Oumuamua2”.
L'IEEC promou i participa en un acte de l’associació Women In Aerospace Europe a Barcelona
El proper 4 d’octubre s’inaugura el capítol local de l’associació Women in Aerospace Europe a Barcelona. Líders dels sectors privat i académic -a través de l’IEEC- participen en una taula rodona per debatre sobre el rol femení en l'àmbit de la ciència i tecnologia de l'espai.
IEEC 4DCube project — third winner of the Open Cosmos and ESA Business Applications “Call to Orbit” competition
The third winner of the “Call to Orbit” competition is a space debris mapping project by the Institute of Space Studies of Catalonia (Institut d’Estudis Espacials de Catalunya, IEEC). 4DCube approach relies on a multidisciplinary team with IEEC members also from the University of Barcelona (UB), the Technical University of Catalonia (UPC) and the Institute of Space Sciences (ICE-CSIC), in Barcelona, Spain.
Capture the Moon with your phone and win a refracting telescope or a binoculars starter kit
On the occasion of the 50th anniversary since the first humans set foot on the Moon, the Institute of Space Studies of Catalonia (IEEC) is launching a social media competition, inviting you to spot the Moon in the sky. The deadline for the social media competition has been extended to 31 August 2019.
The first image of a black hole
25/09/2019 - 00/00/0000
I will briefly discuss how the first image of a black hole was obtained by the EHT collaboration. In particular, I will describe the theoretical aspects that have allowed us to model the dynamics of the plasma accreting onto the black hole and how such dynamics was used to generate synthetic black-hole images.
Spin of primordial black holes
19/09/2019 - 00/00/0000
We discuss the spin of primordial black holes (PBH) formed during radiation domination under the assumption of Gaussian statistics. They are formed by the collapse of rare fluctuations.
Studying the Expansion of the Universe with quasar spectra
13/09/2019 - 00/00/0000
From 2009 to 2014, the Baryon Oscillation Spectroscopic Survey (BOSS) used the SDSS telescope to obtain spectra of 1.5 million galaxies to get very accurate measurements of the Baryon Acoustic Oscillations (BAO) scale at redshift z ~0.5.
Higher spin motivated theories (of gravity)
13/09/2019 - 00/00/0000
Despite the continuing efforts, we cannot be truly satisfied with our understanding of the physics in the UV (short distance) limit. The manifestation is that there is no broadly accepted model of quantum gravity.
