My teacher told me something really important: "It doesn't matter how many times you fall, what matters is that nobody sees you." #wiseman #winterschool #physics #cosmology Joan Bachs Esteban Tonale Winter School of Cosmology

How do we know that there is dark matter if we actually do not see it? Joan talks about one of the signs of its existence 🎦 youtu.be/1-2_cFV6RGI #wearetecnico #técnicostudents #técnicoscientists #técnicoteachers #técnicocommunity #research #astrophysics #outreach

In our last video, Antoine told you that the universe has a finite age. This week, Giorgio and Matteo will explain to you how do we know that! 🎦 youtu.be/EEzKJ3FChpU #wearetécnico #técnicoscientists #Physics #cosmology #research #outreach

My first tweet since the middle-age. It seems natural to spam myself a bit. centra

Tessie 🍉, Joan Bachs Esteban, and Matteo Piani have taken part in the 7th PhD Students Workshop, where they have had the opportunity to learn about their peers' work and get to know each other. Here you have them with the amazing view of Universidade de Coimbra! #phd #learning #research

We've had the pleasure of hosting Lisa Goh from CEA Paris-Saclay and Maciej Kierkla and Mateusz Zych from Uniwersytet Warszawski, collaborators from the ADIEU and COGWAy projects, funded by FCT - Fundação para a Ciência e a Tecnologia 🇵🇹, Ministère Enseignement supérieur/Recherche/Espace 🇫🇷 and NAWA Polish National Agency for Academic Exchange 🇵🇱. Here they are with the Instituto Superior Técnico collaborators!

Now it was the turn of CENTRA PhD students to go abroad! Matteo Piani and Giorgio Laverda have spent a week at Uniwersytet Warszawski and Joan Bachs visited CEA Paris-Saclay, all thanks to the COGWAy and ADIEU projects funded by FCT - Fundação para a Ciência e a Tecnologia 🇵🇹, NAWA Polish National Agency for Academic Exchange 🇵🇱, and Ministère Enseignement supérieur/Recherche/Espace 🇫🇷

New paper out with my student Matteo Piani Matteo Piani centra We demonstrate oscillon formation in #Einstein-Cartan Higgs Inflation, a new feature wrt to metric & Palatini cases. And we have a nice movie! 📹 youtu.be/DDwtx44Cfh0 📋arxiv.org/abs/2304.13056 Complutense

Higgs Inflation strikes back. Oscillons are really amazing and #Einstein-Cartan gravity seems a rather flexible, yet minimal, framework for scalar-tensor theories. Check out the video and the paper youtu.be/DDwtx44Cfh0 arxiv.org/abs/2304.13056 centra

A special thanks to Complutense and IPARCOS-UCM for hosting me in the final phase of this project, and for providing the cluster facility to perform our simulations

Our #YouTube channel has just reached 300 followers! We are delighted to reach this cinematic figure. Check out our videos and official #socialmedia accounts to see all of our #outreach activities! 🎦 youtube.com/@centerforastr… 🪢lnkd.in/dVQ_6_C5

Here you have some pictures of the last #Physics@Coffee! The Instituto Superior Técnico students seemed to be very interested in the research carried out by our group. Matteo Piani Matteo Piani, Joan Joan Bachs Esteban, Ishfaq Rather Rather, João Silvestre, and Santiago Gonzalez got many questions!

For a lucky(?) coincidence, me Chiara Badiali and @canova_martina share the same birthday on the 28th of June. Elon Musk and Sabrina Ferilli, you are invited to join us in Lisbon for the celebration. Details in dm

Opening arXiv after yesterday's International Pulsar Timing Array announcement be like... #GravitationalWaves #PulsarTimingArray #LOTR

New paper out with my PhD studs Matteo Piani & G.Laverda and collaborators at Warsaw Univ .in COGWAY project supported by FCT - Fundação para a Ciência e a Tecnologia NAWA Polish National Agency for Academic Exchange. We showcase a new triggering mechanism for BSM phase transitions in early Universe...and we have a very nice title! arxiv.org/abs/2309.08530

Wishing you a joyous holiday season filled with warmth and inspiration. May the new year bring continued success and discoveries! Desejamos a todos umas festas repletas de alegria e inspiração. Que o novo ano traga sucesso contínuo e novas descobertas! #HappyHolidays #BoasFestas

🔍 New paper out with my PhD student Joan-Bachs Esteban! We explore the impact of #ChameleonMechanism on #WhiteDwarfs, revealing the appereance of a thick-shell configuration for the chameleon leading to reduced radii and masses. #Astrophysics 📖 arxiv.org/abs/2407.04791

🔍 New paper out with F. Goertz, M. Hager from MPIK Heidelberg & my PhD G. Laverda! We revive active-sterile mixing scenarios for #Neutrino #DarkMatter using a time-dependent approach. Discover how our minimal model circumvents X-ray constraints! 📖 📖 arxiv.org/abs/2407.04778

🎉Congrats to Matteo Piani Matteo Piani, Instituto Superior Técnico #PhD student, for earning 3rd place in the Pitch Competition at Técnico PhD Open Days! 🌌👏His presentation showcased his passion for cosmology & science communication 📰 diferencial.tecnico.ulisboa.pt/ciencia/phd-op… #weareTécnico #ScienceCommunication
