Upcoming ITC Seminars

2021 Dec 13

Seminar - Abhijeet Anand (MPI for Astrophysics)

11:00am to 11:30pm

Location: 

Zoom

" The cool CGM in absorption with large spectroscopic surveys"

The gas flows in the circumgalactic medium (CGM) play a pivotal role in several key processes regulating galaxy formation, implying that our understanding of galaxy formation is limited by our current understanding of the CGM. In this talk, I will present the recent constraints that we obtained on the...

" Reconstructing the Cosmic Web at High Noon with Lyman Alpha Tomography"

Cosmic High Noon is defined by the peak of star formation, occurring at z~2.5. Not only is understanding the dynamics of this epoch critical for a unified picture of galaxy formation, but it also plays a critical role in cosmology to connect low redshift measurements to those from the primordial...

Seminar - Zhuo Chen (UCLA)

11:30am to 12:00pm

Location:

" A new window on star formation history at the Galactic Center"

As the closest galactic nucleus, Milky Way's Nuclear Star Cluster (NSC) provides a unique opportunity to resolve the stellar population and to study its composition and star formation in this extreme environment. The limitation in our current understanding of the NSC star formation history is that previous...

Seminar - Jose María Ezquiaga (U Chicago) and Rohan Naidu (Harvard)

11:00am to 12:00pm

Location: 

Zoom

" Probing the standard cosmological model with the population of binary black-holes"

Gravitational-wave (GW) detections are rapidly increasing in number, enabling precise statistical analyses of the population of compact binaries. In this talk I will show how these population analyses cannot only serve to constrain the astrophysical formation channels, but also to learn...

Seminar - Emily Wilson (RIT) and Mohit Bhardwaj (McGill)

11:00am to 12:00pm

Location: 

Zoom

" Convection in Common Envelopes"

The common envelope (CE) phase of binary evolution is the primary theorized mechanism to produce short-period, compact binaries. The efficiency of energy transfer between the two stars of the CE, $\alpha_{CE}$, and the predicted final separations of these same systems are closely linked. Rather than using a constant ejection efficiency,...

Location: 

Zoom

" Recovering the Density Fields inside Quasar Proximity Zones at z~6"

The matter density field at z~6 is very challenging to probe. One of the traditional methods that work successfully at lower redshift is the Lyman-alpha forest in quasar spectra. However, at z~6, the residual neutral hydrogen usually creates saturated absorption, thus much of the information about gas...

" Evolution of Stellar Feedback from Reionization to The Milky Way: A Diverse Toolset of Imaging, Spectroscopy, and Modeling for Understanding the Impact of Massive Stars"

Massive stars contribute incredible amounts of energy to their surroundings across a variety of environments in the universe. Before their exciting deaths, massive stars produce feedback through a...
