The synchronized dance of the Magellanic Clouds star formation history
Stellar mass formed over time in the Small (top) and Large (bottom) Magellanic Clouds (SMC/LMC). For the first time it is revealed that their star formation histories are connected in the last 3.5 billion years (see vertical dashed lines).
The Transient Survey Telescope (TNT) project will install a 1 metre telescope which, in a novel way, will have a wide field of view and will need high capacities of storage and digital processing. The Instituto de Astrofísica de Canarias (IAC) and the Canary Company Light Bridges , with headquarters in Las Palmas de Gran Canaria have recently signe dan agreement which establishes the terms of the cooperation between the two for the installation, setting up, and exploitation of a special telescopic installation called the Transient Survey Telescope (TST) The new telescope will be installed in
In the 90s, the COBE satellite discovered that not all the microwave emission from our Galaxy behaved as expected. Part of this signal was later assigned to a fresh new emission component, spatially correlated with the Galactic dust emission, which showed greater importance in the microwave range of frequencies. It has been named since as “anomalous microwave emission”, or AME. The current main hypothesis to explain the AME origin is that it is emitted by small dust particles which undergo fast spinning movements. In Fernández-Torreiro et al. (2023), we study the observational properties of
Stellar ages are key to several fields of astrophysics such as exoplanet research, galactic-archeology, and of course stellar physics. Obtaining the ages of stars is however not straightforward and requires stellar modeling. The most widely used technique only requires stellar colors or temperature and surface gravity, but the uncertainties are quite large. This technique is most efficient for stars belonging to clusters, as they were born from the same molecular cloud and share the same ages. In the last decades, based on the study of stellar acoustic waves, asteroseismology became the most
