The constrainability of galaxy positions in the -- SFR plane from SED fitting

Sabine Bellstedt, Aaron S. G. Robotham, Luke J. M. Davies +2

Using a sample of 6,029 galaxies from the GAMA survey, we characterise the spread of galaxy property inferences on the M -- SFR plane via Spectral Energy Distribution…

The Roman eXtreme Deep Field (RXDF)

Haojing Yan, Anton M. Koekemoer, Yue Shen +127

The Roman eXtreme Deep Field (RXDF) program is one of the five General Astrophysics Survey (GAS) programs approved for observing time with the Nancy Grace Roman Space Telescope in…

The Structural Abundance Crisis of Massive Galaxies in Current Cosmological Simulations

Hassen M. Yesuf, Connor Bottrell, Luis C. Ho +5

The internal structure of galaxies encodes the complex baryon cycle driven by gas accretion, star formation, and feedback, together with secular evolution and environmentally drive…

Deep Extragalactic VIsible Legacy Survey (DEVILS): Morphologically-selected galaxy merger fractions and their direct comparison to close-pair samples

Melissa F. Fuentealba-Fuentes, Luke J. M. Davies, Aaron S. G. Robotham +4

Galaxy mergers are a central driver of galaxy evolution across cosmic time, and thus, quantifying their frequency is critical for constraining hierarchical models of galaxy formati…

PEARLS: Two Distinct Populations of AGN Hosts Moving Between Star Formation and Quiescence

Gibson B. Bowling, Rafael Ortiz, S. P. Willner +29

We present the results of AGN--host-galaxy decomposition using JWST/NIRCam, HST/ACS, and HST/WFC3 imaging of the North Ecliptic Pole Time Domain Field (NEP-TDF). The light-profiles…

DINGO/GAMA /WAVES: HI-halo mass relation

Ajay Dev, Martin Meyer, Simon P. Driver +17

We investigate the relation between neutral atomic hydrogen (HI) and dark matter halo mass (HIHM) using observations from the Deep Investigation of Neutral Gas Origins (DINGO) pilo…

Decomposing the growth mechanisms of galaxies over the last 10 billion years

Luke J. M. Davies, Annagrazia Puglisi, Marcella Longhetti +10

Determining how galaxies accumulate stellar mass is paramount to understanding the Universe. Two primary mechanisms drive this process: star-formation (SF) & mergers. Our understan…

The contribution of stars, dust, neutral gas and supermassive black holes in galaxies to the cosmic baryon inventory

Jordan C. J. D'Silva, Simon P. Driver, Aaron S. G. Robotham +5

We compute the cosmic stellar, dust and neutral gas mass history at using ProSpect spectral energy distribution modelling of galaxies in the Gal…
