Network in Neutrinos, Nuclear Astrophysics, and Symmetries (N3AS) Seminar
A status update on the Galactic Center GeV gamma-ray excess
Time: 2:00 pm
Place: Join Zoom Meeting Meeting ID: 912 3071 4547
Speaker: Tracy Slatyer , MIT
Abstract: The inner region of the Milky Way Galaxy hosts a central glow of gamma rays often called the Galactic Center Excess. This excess is highly statistically significant and has garnered great interest as a possible signal of either dark matter particles colliding and annihilating, or a previously undiscovered population of pulsars in the stellar bulge. I will briefly outline the history of our understanding of the excess and the arguments for various interpretations, attempt to describe the current status of the controversy including recent developments, and discuss some future paths forward.

MRSEC Seminar
New Frontiers in Nanoscale Magnetism: Towards Three-Dimensional Materials and Devices
Time: 3:00 pm
Place: Materials Science & Engineering Building, Room 265
Speaker: Amalio Fernández-Pacheco, Institute of Nanoscience & Materials of Aragón CSIC-University of Zaragoza, Spain
Abstract: The expansion of nanomagnetism to three dimensions provides exciting opportunities to explore new physical phenomena and opens great prospects to create 3D magnetic devices for green computing technologies.
In this talk, I will present some of our recent works dedicated to the investigation of three dimensional artificial magnetic materials, including multilayered and complex-shaped geometries. The talk will give an overview of the new methods we have developed to fabricate and characterize these nanomaterials, and some of the new functionalities obtained. This includes the creation of localized spin textures, topological defects and stray fields exploiting geometrical effects, the automotive 3D motion of domain walls, and the generation of chiral spin interactions via geometry and interfacial effects.

Theory Seminar (High Energy/Cosmology)
Cosmological Constant and Gravitino Mass: Statistical Correlations from the Nilpotent Goldstino Formalism.
Time: 4:00 pm
Place: Chamberlin 5280
Speaker: Kajal Singh, Harish-Chandra Research Institute
Abstract: We obtain the joint distribution function of the gravitino mass and the cosmological constant in KKLT and Large Volume Scenario models with an anti-D3 brane at the bottom of a warped throat as the uplift sector. Moduli stabilisation is incorporated so that we sample only over points corresponding to vacua. The effects of the anti-D3 brane are computed using the nilpotent goldstino formalism. The distribution function for the hierarchies of warped throats serves as a key input. In the limit of zero cosmological constant, we find that the distribution functions are tilted favourably towards lower scales of supersymmetry breaking.
