The MAGPI Survey: forward modelled gas-phase metallicity gradients in galaxies at

Yifan Mai, Scott M. Croom, Emily Wisnioski +19

We measure the seeing-deconvolved gas-phase metallicity gradients of 70 star-forming galaxies at from the MAGPI survey and investigate their relationship with galaxy pr…

DELVE Milky Way Satellite Galaxy Census I: Satellite Population and Survey Selection Function in DES, DELVE, and Pan-STARRS

C. Y. Tan, A. Drlica-Wagner, A. B. Pace +84

The properties of Milky Way satellite galaxies have important implications for galaxy formation, reionization, and the fundamental physics of dark matter. However, the population o…

Search for Slow Bars in Two Barred Galaxies with Nuclear Structures: NGC 6951 and NGC 7716

Yun Hee Lee, Ho Seong Hwang, Virginia Cuomo +9

We investigate two barred galaxies with nuclear structures, NGC 6951 and NGC 7716, to examine whether they host slow bars. Using Gemini/GMOS long-slit spectroscopy, we calculate th…

GAMA 526784: the progenitor of a globular cluster-rich ultra-diffuse galaxy? I. Star clusters, stellar body and ionised gas properties

Maria Luisa Buzzo, Michael Hilker, Anita Zanella +4

Context. Ultra-diffuse galaxies (UDGs) are an intriguing population of galaxies. Despite their dwarf-like stellar masses and low surface brightness, they have large half-light radi…

Galaxy And Mass Assembly: A new approach to quantifying dust in galaxies

B. Farley, U. T. Ahmed, A. M. Hopkins +8

We introduce a new approach to quantifying dust in galaxies by combining information from the Balmer decrement (BD) and the dust mass (). While there is no explicit correlatio…

EMU/GAMA: A new approach to characterising radio luminosity functions

J. Prathap, A. M. Hopkins, J. Afonso +16

This study characterises the radio luminosity functions (RLFs) for SFGs and AGN using statistical redshift estimation in the absence of comprehensive spectroscopic data. Sensitive…

A Redshift Survey of the Coma Cluster (A1656): Understanding the Nature of Subhalos in the Weak-lensing Map

Wooseok Kang, Ho Seong Hwang, Nobuhiro Okabe +1

We study the physical properties of weak-lensing subhalos in the Coma cluster of galaxies using data from galaxy redshift surveys. The data include 12989 galaxies with measured spe…
