Mapping reionization bubbles in the JWST era I: empirical edge detection with Lyman alpha emission from galaxies
Ting-Yi Lu, Charlotte A. Mason, Andrei Mesinger +7
Ionized bubble sizes during reionization trace physical properties of the first galaxies. JWST's ability to spectroscopically confirm and measure Lyman-alpha (Ly) emission in su…
Semi-analytic modelling of Pop. III star formation and metallicity evolution -- I. Impact on the UV luminosity functions at z = 9-16
Emanuele M. Ventura, Yuxiang Qin, Sreedhar Balu +1
We implemented Population III (Pop. III) star formation in mini-halos within the MERAXES semi-analytic galaxy formation and reionisation model, run on top of a N-body simulation wi…
Accelerated Formation of Ultra-Massive Galaxies in the First Billion Years
Mengyuan Xiao, Pascal Oesch, David Elbaz +35
Recent JWST observations have revealed an unexpected abundance of massive galaxy candidates in the early Universe, extending further in redshift and to lower luminosity than what h…
Implications of JWST galaxies for galaxy formation at high redshift
Yuxiang Qin, Sreedhar Balu, J. Stuart B. Wyithe
Using a semi-analytic galaxy-formation model, we study analogues of 8 recently discovered JWST galaxies at . We select analogues from a cosmological simulation with a $…
The reionising bubble size distribution around galaxies
Ting-Yi Lu, Charlotte Mason, Anne Hutter +4
Constraining when and how reionisation began is pivotal for understanding when the first galaxies formed. Lyman-alpha (Ly) emission from galaxies is currently our most promising…
Dark-ages reionization and galaxy formation simulation -- XXI. Constraining the evolution of the ionizing escape fraction
Simon J. Mutch, Bradley Greig, Yuxiang Qin +2
The fraction of ionizing photons that escape their host galaxies to ionize hydrogen in the inter-galactic medium (IGM) is a critical parameter in analyses of the reionization era.…
The 21-cm signal from the Cosmic Dawn: metallicity dependence of high mass X-ray binaries
Harman Deep Kaur, Yuxiang Qin, Andrei Mesinger +3
X-rays from High-Mass X-ray Binaries (HMXBs) are likely the main source of heating of the intergalactic medium (IGM) during Cosmic Dawn (CD), before the completion of reionization.…
Linking Extragalactic Transients and their Host Galaxy Properties: Transient Sample, Multi-Wavelength Host Identification, and Database Construction
Yu-Jing Qin, Ann Zabludoff, Marina Kisley +7
Understanding the preferences of transient types for host galaxies with certain characteristics is key to studies of transient physics and galaxy evolution, as well as to transient…
Dark-ages reionization and galaxy formation simulation -- XVIII. The high-redshift evolution of black holes and their host galaxies
Madeline A. Marshall, Simon J. Mutch, Yuxiang Qin +2
Correlations between black holes and their host galaxies provide insight into what drives black hole-host co-evolution. We use the Meraxes semi-analytic model to investigate the gr…
Dark-ages Reionization and Galaxy Formation Simulation -- XVII. Sizes, angular momenta and morphologies of high redshift galaxies
Madeline A. Marshall, Simon J. Mutch, Yuxiang Qin +2
We study the sizes, angular momenta and morphologies of high-redshift galaxies using an update of the Meraxes semi-analytic galaxy evolution model. Our model successfully reproduce…
The first Super Massive Black Holes: indications from models for future observations
Stergios Amarantidis, José Afonso, Hugo Messias +12
We present an exploration of the expected detection of the earliest Active Galactic Nuclei (AGN) in the Universe from state-of-art galaxy formation and evolution semi-analytic mode…
Dependence of galaxy clustering on UV-luminosity and stellar mass at
Yisheng Qiu, J. Stuart B. Wyithe, Pascal A. Oesch +6
We investigate the dependence of galaxy clustering at on UV-luminosity and stellar mass. Our sample consists of 10,000 Lyman-break galaxies (LBGs) in the XDF…
Dark-ages Reionization and Galaxy Formation Simulation - XV. Stellar evolution and feedback in dwarf galaxies at high redshift
Yuxiang Qin, Alan R. Duffy, Simon J. Mutch +3
We directly compare predictions of dwarf galaxy properties in a semi-analytic model (SAM) with those extracted from a high-resolution hydrodynamic simulation. We focus on galaxies…
Dark-ages Reionization and Galaxy Formation Simulation - XIII. AGN quenching of high-redshift star formation in ZF-COSMOS-20115
Yuxiang Qin, Simon J. Mutch, Alan R. Duffy +4
Massive quiescent galaxies (MQGs) are thought to have formed stars rapidly at early times followed by a long period of quiescence. The recent discovery of a MQG, ZF-COSMOS-20115 at…
