The Astrophysical Journal LettersRecent James Webb Space Telescope observations have revealed a peculiar class of galaxies at redshifts z ≳ 6, characterized by extremely high central stellar densities and overmassive central supermassive black holes (SMBHs), “little red dots” (LRDs). A

Molecular Ecology Resources, EarlyView.ABSTRACT As human activities drive biodiversity decline, effective biomonitoring is more crucial than ever to track species distribution changes and inform conservation and restoration actions. Environmental DNA (eDNA) metabarcoding has emerged as a promising tool for the simultaneous detection of multiple taxa. However, while substrates play a crucial

The Astrophysical JournalThe formation pathways of lenticular galaxies (S0s) in field environments remain a matter of debate. We utilize the cosmological hydrodynamic simulation, NewHorizon , to investigate the issue. We select two massive star formation quenched S0s as our main

The Baryon Cycle In Galaxy Mergers
, 2017 Galaxy mergers are well known to dramatically alter not only morphology and structure, but also the internal constituents of galaxies. In this talk I will focus on the baryon cycle within galaxy mergers, whereby gas is converted to stars, which ultimately enriches the ISM with metals. I will present new results that combine measurements of both neutral

The Role of galaxy mergers in the evolution of massive galaxies
, 2014 This Thesis presents a study of the nature of the different stages of galaxy mergers that lead to the formation of massive galaxies. In particular we look into the properties of infrared bright mergers, spheroidal post-mergers and star-forming early-types and how their properties compare and contrast with the properties of regular late and early-type ...

Molecular Ecology Resources, EarlyView.ABSTRACT Quaternary climatic fluctuations had a substantial influence on ecosystems, species distribution, phenology and genetic diversity, driving extinction, adaptation and demographic shifts during glacial periods and postglacial expansions. Integration of genomic data and environmental niche modelling can provide valuable insights on how organisms ...

A Dual Active Black Hole Candidate with Mass Ratio ~7:1 in a Disk Galaxy
The Astrophysical Journal LettersDual active galactic nuclei (AGNs) with comparable masses are commonly witnessed among the major merged galaxies with interaction remnants. Considering almost every massive galaxy is associated with multiple dwarf satellites around it, minor mergers ...

Cell‐Surface LAMP1 is a Senescence Marker in Aging and Idiopathic Pulmonary Fibrosis
Aging Cell, EarlyView.We have validated the selective upregulation of LAMP1 in SEN in culture, and the percentage of Lamp1+ cells increases in various tissues with age, as well as in fibrotic lungs following BLM instillation. The RNA‐Sequencing analysis of the Lamp1‐enriched populations confirmed the enrichment of senescence‐related genes.
