The MAGPI Survey: Evidence for Non-Universal Resolved Dust Attenuation Relations Beyond the Local Universe
A. Mailvaganam, T. Zafar, P. Corcho-Caballero +39
We study the spatially resolved relation between dust attenuation () and star formation rate surface density () in galaxies from the MAGPI survey ($0.25 < z…
A Census of Double-Peaked Lyman-alpha Emitters in MAGPI: Classification, Global Characteristics, and Spatially Resolved Properties
Tamal Mukherjee, Tayyaba Zafar, Themiya Nanayakkara +17
Double-peaked Ly profiles provide critical insights into gas kinematics and the distribution of neutral hydrogen (HI) from the interstellar to the intergalactic medium (ISM to…
EMU/GAMA: Refining Dust Extinction Corrections for Hα Luminosity Functions Using Radio-Based Calibration
J. Willingham, A. Hopkins, T. Zafar +17
We present a novel approach to correcting H luminosity functions for dust extinction by calibrating against radio-based star formation rates (SFRs), using data from the Evoluti…
EMU/GAMA: A statistical perspective on active galactic nuclei diagnostics
J. Prathap, A. M. Hopkins, R. Carvajal +19
While it is well known that galaxies are composites of many emission processes, quantifying the various contributions remains challenging. In this work, we use unsupervised machine…
Predicting Resolved Dust Attenuation from Local Galaxy Properties Using MaNGA
Anilkumar Mailvaganam, Tayyaba Zafar, Pablo Corcho-Caballero +4
Accurate spatially resolved dust corrections are critical for interpreting the structure and evolution of star-forming galaxies (SFGs). We present an empirical model for predicting…
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…
