GOATS: The next generation software infrastructure for time-domain astronomy at Gemini/NOIRLab. Application to alerts from Vera C. Rubin Observatory's Legacy Survey of Space and Time
Monika Soraisam, Louis Avner, Miguel Gómez +38
Time-domain and multimessenger astronomy (MMA/TDA) targets demand rapid-response follow-up observations. In many cases, it is the only way to make discoveries and advance our under…
Picard rank and Ulrich line bundles on bidouble planes
Jerson Caro, Juan Cruz-Penagos, Sergio Troncoso
We determine the Picard number and the Ulrich complexity of general bidouble covers of the projective plane, providing the first systematic study of Ulrich bundles on non-cyclic ab…
Invariant Smooth Quartic Surfaces by all Finite Primitive Groups of
Jose Avila, Guillermo Ortiz, Sergio Troncoso
For each finite primitive subgroup of , we find all the smooth -invariant quartic surfaces. We also find all the faithful representations i…
Projective manifolds whose tangent bundle is Ulrich
Vladimiro Benedetti, Pedro Montero, Yulieth Prieto Montañez +1
In this article, we give numerical restrictions on the Chern classes of Ulrich bundles on higher-dimensional manifolds, which are inspired by the results of Casnati in the case of…
Savage Surfaces
Sergio Troncoso, Giancarlo Urzúa
Let be the topological fundamental group of a given nonsingular complex projective surface. We prove that the Chern slopes of minimal nonsingular projective s…
