Prof. Luis Ho (Kavli Institute for Astronomy and Astrophysics, Peking University)1/5/26, 9:15 AMCC05: Galaxies, AGNs, Black Holes and CosmologyTalk
Supermassive black holes are ubiquitous in the nearby Universe. Their lifecycle appears to be closely connected to the evolution of galaxies. How and when did these mysterious objects form? What was the first generation of black hole seeds? How did they grow quickly enough to power the most distant quasars? And how precisely do black holes co-evolve with galaxies? I will summarize the...

Prof. Rodrigo Herrera-Camus (Universidad de Concepción)1/5/26, 11:00 AMCC05: Galaxies, AGNs, Black Holes and CosmologyTalk
In this talk, I will present Chile-based efforts, carried out in close international collaboration, to understand how, where, and when galaxies evolve across cosmic time. By combining observations from ALMA and JWST/NIRCam+NIRSpec, we are investigating the multi-phase interstellar medium (ISM) in galaxies on kiloparsec scales during the first billion years of the Universe. These studies reveal...

Prof. Ezequiel Treister (Universidad de Tarapaca)1/6/26, 9:00 AMCC05: Galaxies, AGNs, Black Holes and CosmologyTalk
Dual AGN at kiloparsec separations mark the phase of most rapid supermassive black hole growth, but systematic discovery is hindered by extreme obscuration (N$_H$$>$10$^{24}$ cm$^{-2}$). I present a new method that combines ALMA millimeter continuum observations with hard X-ray data to identify these systems.
The mm/X-ray luminosity correlation traces SMBH accretion from the innermost...

Prof. Feng Yuan (Fudan University)1/6/26, 11:00 AMCC05: Galaxies, AGNs, Black Holes and CosmologyTalk
In this talk, I will review our series of works on AGN feedback in a galactic scale based on the MACER framework. The key features of the MACER model are that: 1) it focuses on the galactic scale; 2) the inner boundary of the simulation domain is smaller than the Bondi radius thus we can reliably determine the mass accretion rate of the black hole; and 3) the state-of-the-art accretion...

Prof. Linhua Jiang (Peking University)1/6/26, 11:25 AMCC05: Galaxies, AGNs, Black Holes and CosmologyTalk
JWST has uncovered a new population of compact objects that show a unique V-shaped SED in the UV and optical wavelength range. These so-called Little Red Dots (LRDs) often exhibit broad Balmer emission lines, indicative of the presence of AGNs. They generally lack detection of X-ray, radio, and mid-IR radiation, which is fundamentally different from typical AGNs. My team recently made...

Prof. Siwei Zou (CASSCA/NAOC)1/6/26, 11:50 AMCC05: Galaxies, AGNs, Black Holes and CosmologyTalk
The growth of galaxies and their central supermassive black holes (SMBHs) is regulated by multiphase gas in the circumnuclear and star-forming regions, as well as in the circumgalactic environment. These gas phases range from cold molecular clouds to warm ionized gas and hot diffuse halos, transporting metals, dust, and angular momentum that influence both star formation and black hole...

Prof. Chao-Wei Tsai (National Astronomical Observatories, Chinese Academy of Sciences)1/6/26, 4:00 PMCC05: Galaxies, AGNs, Black Holes and CosmologyTalk
Neutral hydrogen (HI) serves as an effective tracer of galactic internal dynamics, gas accretion, and feedback activity. Deep integrations of the nearby spiral galaxy M31 with the FAST telescope, when combined with interferometric data, reveal clear correlations between stellar feedback and both the kinematics and spatial distribution of atomic gas and the surrounding interstellar medium. For...

Dr Pablo García (NAOC)1/7/26, 9:00 AMCC02: ISM and AstrochemistryTalk
The Central Molecular Zone (CMZ) of the Milky Way primarily controls the gas flow from the disc of the Galaxy towards the central nucleus. The CMZ is well-documented to have extreme gas properties that clearly distinguish it from the rest of the Galaxy. While this region has been the subject of intense research, the CMZ-wide properties of the molecular gas at high angular resolution are...

Prof. Tie Liu (Shanghai Astronomical Observatory)1/7/26, 9:25 AMCC01: Star formation (including late stage stellar evolution)Talk
To statistically investigate the star formation process in the Galaxy, we initiated the ALMA-ATOMS/QUARKS survey programme at ALMA, which observed about 140 high-mass proto-clusters at band 3 and band 6 under an angular resolution of ~0.3-2 arcsec. The main science goals of the ALMA-ATOMS/QUARKS survey project are: (i) to deepen the understandings of the dense gas star formation law by...

Prof. Xuan Fang (NAOC)1/8/26, 11:00 AMCC01: Star formation (including late stage stellar evolution)Talk
Planetary nebulae (PNe) are probes of late-stage stellar evolution, and also key tracers of the stellar population, chemistry and kinematics of host galaxies; they are the only emission-line ISM that exist in almost every part of a galaxy, from bulge and disk to the outer halo. I will report new results from our deep spectroscopy of PNe in the Milky Way and Andromeda (M31) using the 10.4m GTC...

Prof. Gongbo Zhao (NAOC)1/9/26, 11:00 AMCC05: Galaxies, AGNs, Black Holes and CosmologyTalk
Large-scale structure has become a precision laboratory for testing gravity and dark energy. I will present recent results from our multi-tracer analyses of SDSS-IV/eBOSS luminous red and emission-line galaxies, using both configuration- and Fourier-space approaches. A key element is a “chained” multipole estimator that suppresses angular systematics, enabling robust use of auto- and...

Bruno Dias (Universidade Andrés Bello)CC04: Stars and Stellar ClustersTalk
Star clusters are powerful tools for studying stellar evolution when analyzed individually. Certain combinations of global parameters of star clusters in the Milky Way have led to a bimodal classification: old, massive globular clusters and young, low-mass open clusters. The star clusters found in the Magellanic Clouds exhibit a range of global parameters and internal structures that...

Prof. Ricardo Munoz (Universidad de Chile)CC04: Stars and Stellar ClustersTalk
According to our currently favored cosmological framework, the Lambda- Cold Dark Matter model, galaxies like the Milky Way were built through the accretion and merger of smaller systems. In this scenario, the extended halo of the Milky Way must retain information about this process. Key to unveiling this information is our ability to trace the outermost regions of the halo by detecting and...
