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...
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...
In this talk, I will introduce the ongoing concept development of a 2-meter class space ultraviolet (UV) mission designed to achieve high-sensitivity, spectroscopic, and pointing observation capabilities extending into the far-ultraviolet (FUV, 90–200 nm) regime. The mission aims to address key astrophysical questions concerning the ionized interstellar and intergalactic medium, the physics of...
The Chinese Space Station Survey Telescope (CSST) is an upcoming Stage-IV sky survey telescope, distinguished by its large field of view (FoV), high image quality, and multi-band observation capabilities. It can simultaneously conduct precise measurements of the Universe by performing multi-color photometric imaging and slitless spectroscopic surveys. The CSST is equipped with five scientific...

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...
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...
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...
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...
TBD
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...
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...
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...
This project has been the natural evolution of our outreach work at the “Instituto de Estudios Astrofísicos” of Diego Portales University (UDP), which since 2016 has focused mainly on 2 lines: Astronomical Art and Inclusive Astronomy.
Working together with poets, we have managed to merge both lines in transdisciplinary experiences where the public is the one who communicates astronomy in a...
In this talk I will introduce the astronomy department at U. Chile, from their historical context to the current main areas of research as well as important tasks relevant to the national astronomical community and the Chilean population at large.
In this talk, I will present some of the latest observational results for understanding the life cycle of galactic ecosystems, including both nearby and high-redshift galaxies. I will first present new results on galaxy demographics in the early universe made possible by recent JWST studies, and then discuss more generally what we have learned in recent years about the fundamental physics...
Mapping the circumgalactic medium (CGM) in emission is one of the important scientific goals for astronomers to either use the modern ground-based telescopes or the future space missions.CGMs are multi-phases, key to understand the galaxy ecosystem and its accretion and feedback.In this talk, I will introduce a few scientific projects in our group for the efforts in the warm and hot diffuse...
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...
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...
A new time domain ecosystem is developing thanks to a new generation of large aperture and large field of view telescopes, notably the Vera C. Rubin Observatory. Among the tools required are fast machine learning aided discovery and classification algorithms, interoperable tools to allow for an effective communication with the community and follow-up telescopes, and new models and tools to...
Extragalactic Fast X-ray Transients (FXTs), manifesting as a few minutes to hours X-ray flashes, have likely been observed since the 1970s, but only a few dozen examples have been isolated as non-Galactic objects thanks to archival Chandra, XMM-Newton, and Swift data over the past two decades. The launch of Einstein Probe in 2024, which can rapidly detect and localize FXTs in its 3600 deg2 FOV...
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...
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...
The universe is filled with mysterious events that provide vital insights into the fundamental processes of astrophysical systems. Identifying anomalies within normal populations remains a significant challenge, as astronomers must detect and characterize them in real-time.
In this talk, we will explore how the ALeRCE broker is transforming the way we track and discover cosmic anomalies,...
