All Hands on Deck: What observations, theory, simulation and laboratory experiments are teaching us about the powerful AGN jets

SLAC, Kavli 3rd Floor Conf. Room

Speaker
Hui Li (Los Alamos)

Powerful jets from active galactic nuclei (AGNs) are observed on scales from Mpc down to astronomical units, from essentially all observable wavebands and via multi-messengers.

Probing the assembly of the youngest and most embedded stars

Stars form in dense clouds of gas and dust, and this material greatly obscures the central cores of still-forming stars. However, some radiation does escape from their circumstellar envelopes and disks, allowing some study of these youngest stars. This even includes Class 0 protostars, stars so young that they have yet to accrete the majority of their mass. We have recently observed the first absorption spectrum of the photosphere of a Class 0 protostar, S68N in Serpens.

Is our Solar System Unique? A Holistic View of Exoplanet Demographics

Campus, PAB 102/103

Speaker
BJ Fulton (Caltech)

The Kepler and K2 missions blessed the community with a plethora of planet transit detections which enabled studies of exoplanet size demographics. Much of the recent progress in this field is driven by improved characterization of the stellar hosts. Our group recently used precise radius measurements from the California-Kepler Survey (CKS) to detect a gap in the distribution of planet radii.
