LIMFAST. I. A Seminumerical Tool for Line Intensity Mapping

open access: yesThe Astrophysical Journal, 2023
We present LIMFAST, a seminumerical code for simulating high-redshift galaxy formation and cosmic reionization as revealed by multitracer line intensity mapping (LIM) signals.

Globular cluster formation and evolution in the context of cosmological galaxy assembly: open questions [PDF]

open access: yesProceedings of the Royal Society A, 2018
We discuss some of the key open questions regarding the formation and evolution of globular clusters (GCs) during galaxy formation and assembly within a cosmological framework.

LIMFAST. II. Line Intensity Mapping as a Probe of High-redshift Galaxy Formation

open access: yesThe Astrophysical Journal, 2023
The epoch of reionization (EoR) offers a unique window into the dawn of galaxy formation, through which high-redshift galaxies can be studied by observations of both themselves and their impact on the intergalactic medium.

The formation and evolution of black holes

open access: yesTheoretical and Natural Science, 2023
The concept of Black Holes was first introduced as a prediction by Eisteins Theory of General Relativity and later solved by the Schwarzschild Solution in 1915.

New Insight on Galaxy Formation and Evolution from Keck Spectroscopy of the Hawaii Deep Fields [PDF]

open access: yes, 1996
We present the results of spectroscopic studies with the LRIS spectrograph on Keck of two of the Hawaii deep survey fields. The 393 objects observed cover an area of 26.2 square arcmin and constitute a nearly complete sample down to K = 20, I = 23, and B

DESI Survey Validation Data in the COSMOS/Hyper Suprime-Cam Field: Cool Gas Trace Main-sequence Star-forming Galaxies at the Cosmic Noon

open access: yesThe Astrophysical Journal, 2023
We present the first result in exploring the gaseous halo and galaxy correlation using the Dark Energy Spectroscopic Instrument survey validation data in the Cosmic Evolution Survey (COSMOS) and Hyper Suprime-Cam field.

Scaling Properties of Galaxy Groups

open access: yesUniverse, 2021
Galaxy groups and poor clusters are more common than rich clusters, and host the largest fraction of matter content in the Universe. Hence, their studies are key to understand the gravitational and thermal evolution of the bulk of the cosmic matter ...

Dust-regulated galaxy formation and evolution: a new chemodynamical model with live dust particles [PDF]

open access: yes, 2015
Interstellar dust plays decisive roles in the conversion of neutral to molecular hydrogen (H_2), the thermodynamical evolution of interstellar medium (ISM), and the modification of spectral energy distributions (SEDs) of galaxies.

Retracted: Can the chemical industry solve the climate change?On the role of human energy production, renewable energies, and the potential of chemistry as a solution provider

open access: yesChemie Ingenieur Technik, EarlyView., 2023
Let us consider an alternative perspective on climate change: The sum of solar radiation and heat generated by human activity result in a net energy input of 1.96 times that of the Sun on the Earth's surface. The expanding global population is expected to exacerbate this issue. Potential solutions are proposed, including replacement and heat recycling.

Globular cluster formation in the context of galaxy formation and evolution [PDF]

open access: yes, 2014
The formation of globular clusters (GCs) remains one of the main unsolved problems in star and galaxy formation. The past decades have seen important progress in constraining the physics of GC formation from a variety of directions.
