Resolving the clumpy circumstellar environment of the B[e] supergiant LHA 120-S 35 Andrea F. Torres, Lydia S. Cidale, Michaela Kraus, María L. Arias, Rodolfo H. Barbá, Grigoris Maravelias, Marcelo Borges Fernandes B[e] supergiants (SGs) are massive post-main-sequence stars, surrounded by a complex circumstellar (CS) environment. The aim of this work …
A few weeks ago couple of months ago I gave a small talk during the journal club of the Astronomy group at the University of Crete (on 20/Oct/2017) about the most recent gravitational wave detection (GW170817) corresponding to a neutron star merger. As I have been involved in a couple …

Bruzual, G. Maravelias, D. Zaritsky, S. Charlot, V. H. Ramirez-Siordia We present a new study of the spatial distribution and ages …
A new era, of multi-messenger astronomy (combining gravitational waves, particles, photons), has been born today. LIGO/VIRGO plus 70 teams around the world announced the first detection of colliding neutron stars, which means that a gravitational wave detection (GW170817) triggered the observations using almost everything available (from gamma rays to radio …
I think it had everything: – waking up early to go to the bank, – then go to the university and finalize some aspects of my talk (as a final contribution), – go for lunch with the whole group, – return to the university, – to say goodbye to people, …
