Astro Tuesday: Ava Polzin and Karia Dibert

12:00–1:00 pm ERC 501

Host: Austin Joyce

Ava Polzin "The Phase Space of X-ray Transients Out to z = 1"

The duration-luminosity phase space (DLPS) is often used to contextualize transient signals, identifying areas of interest (i.e., regions in the parameter space where detections are expected but not observed) and providing initial qualitative guidance in classifying new transient observations. I will discuss where each class of soft X-ray transient exists in the 0.3 - 10 keV DLPS. With an eye toward the discovery space, I will address the state of current and planned/proposed X-ray telescopes and their anticipated role in transient detection and characterization.

Karia Dibert "Microwave Kinetic Inductance Detectors for CMB observation with the South Pole Telescope"

Microwave Kinetic Inductance Detectors (MKIDs), are a highly sensitive, highly multiplexible detector technology that allows for densely packed focal planes with minimal readout complexity. I will talk about how MKIDs operate and their advantages for future CMB experiments. I will then go over the design for the planned SPT-3G+ focal plane and explain how the SPT-3G+ science goals influenced the pixel design. I'll also talk about how these detectors are fabricated and tested here in the ERC basement. There will be a show-and-tell component.
