JHU/STScI CAS Wine and Cheese Seminars take place in Bloomberg 462 every Monday at 3:30 pm Eastern. Each week, there will be either one speaker, giving an hour-long presentation (50+10), or two speakers, each giving a half hour (25+5) presentation. Hour-long speakers will be invited by the committee, and the half-hour speakers will comprise both […]
Informal science discussions and coffee, open to the entire department.
We meet every Tuesday at 1pm, Eastern time, in the CafeCon (the conference room next to the STScI cafeteria), and also remotely using BlueJeans. We start with a talk by guest speaker for ~30 minutes, followed by paper discussion. Vote for what papers you want discussed on Benty-Fields. Sign up for e-mails by sending a […]
Title: The hyperbolic tale of GW190521 Abstract: I will discuss the most enigmatic signal observed by the LIGO-Virgo-Kagra collaboration to date, GW190521, and the possibility that it was generated by the merger of two massive black holes in non-circular orbits. A critical comparison with the standard hypothesis of a quasi-circular binary will be presented, together […]
Title: Moiré magnetism in twisted two-dimensional magnets Abstract: Moiré superlattice emerges from the interference between two mismatched atomic lattices, and it has led to tremendous success in designing and tailoring the electronic states in two-dimensional (2D) homo- and hetero-structures. Yet, the power of moiré superlattice in controlling the spin degree of freedom and thus modifying the magnetic states is much less […]
