Title: Multi-messenger signals from magnetized core-collapse supernovae

Speaker: Associate Professor Kuo-Chuan Pan
(Institute of Astronomy, National Tsing Hua University)

Place: Science Building III SC157

Abstract:

Core-collapse supernovae (CCSNe) are among the most explosive events in the universe and are the birthplaces of neutron stars and stellar-mass black holes under extreme conditions. CCSNe are also ideal multi-messenger sources, expected to be detected not only through electromagnetic waves but also via neutrinos and gravitational waves.
In this talk, I will present the latest results from our multi-dimensional supernova simulations with self-consistent neutrino transport. In particular, I will focus on how magnetic fields and stellar rotation affect the explosion engine and multi-messenger signals. I will also comment on further searches for gravitational waves from core-collapse supernovae.

11/28 Probing entanglement dynamics on NISQ computers

Title: Probing entanglement dynamics on NISQ computers

Speaker: Associate Professor Hsiu-Chuan Hsu
(Graduate Institute of Applied Physics, National Chengchi University)

Place: Science Building III SC157

Abstract:

The quench dynamics of the Su-Schierffer-Heeger (SSH) chain is simulated on IBM Quantum computers. The second-order Rényi entanglement entropy, the twist order parameter and the Berry phase are calculated and shown persistent oscillations. Through error mitigation techniques, including global depolarizing error ansatz and postselection based on symmetry constraints, the simulation results match closely to the exact solution. Along with this research, a software tool is developed for effective simulation of entanglement entropy and a patent for monitoring quantum computers is granted.

10/17 Cosmic Ray Feedback in the Universe: Fermi Bubbles and Odd Radio Circles

Title: Cosmic Ray Feedback in the Universe: Fermi Bubbles and Odd Radio Circles

Speaker: Associate Professor Hsiang-Yi Karen Yang
(Institute of Astronomy, National Tsing Hua University)

Place: Science Building III SC157

Abstract:

Relativistic jets from supermassive black holes (SMBHs) are vital drivers of massive galaxy properties, and cosmic rays (CRs) within SMBH jets have shown to be a key ingredient in the process. It is therefore crucial to model the effects of CRs self-consistently in numerical simulations. In this talk, I will present how we could apply 3D CR-magnetohydrodynamic (MHD) simulations to understand enigmatic phenomena in the Universe, including the Fermi bubbles within the Milky Way Galaxy, as well as the newly discovered odd radio circles (ORCs). Our investigations suggest that both phenomena could be explained by powerful jet activity of SMBHs.

5/30 Toward a better understanding of galaxy formation in ΛCDM: part II

Speaker: Dr. Yen-Ting Lin (Research Fellow)
(Institute of Astronomy and Astrophysics, Academia Sinica)
Place: Science Building III SC157
Abstract:
I will continue my unfinished talk from last year(!) and provide a general overview of our current understanding of how galaxies form in the framework of the standard model of cosmology. I will review the success and potential problems ΛCDM faces in producing the galaxy population we observe, and finish with our recent validation of ΛCDM using the most massive galaxies in the universe.
