An Integral Field Study of Abundance Gradients in Nearby LIRGs

J. A. Rich, P. Torrey, L. J. Kewley +2

We present for the first time metallicity maps generated using data from the Wide Field Spectrograph (WiFeS) on the ANU 2.3m of 9 Luminous Infrared Galaxies (LIRGs) and discuss the…

FIRST J1419+3940 as the First Observed Radio Flare from a Neutron Star Merger

K. H. Lee, I. Bartos, G. C. Privon +2

During their violent merger, two neutron stars can shed a few percent of their mass. As this ejecta expands, it collides with the surrounding interstellar gas, producing a slowly-f…

CASCO: Cosmological and AStrophysical parameters from Cosmological simulations and Observations IV. Testing warm dark matter cosmologies with galaxy scaling relations: A joint simulation-observation study using DREAMS simulations

M. Silvestrini, C. Tortora, V. Busillo +9

Small-scale discrepancies in the standard Lambda cold dark matter paradigm have motivated the exploration of alternative dark matter (DM) models, such as warm dark matter (WDM). We…

A Deep Learning Approach to Galaxy Cluster X-ray Masses

M. Ntampaka, J. ZuHone, D. Eisenstein +9

We present a machine-learning approach for estimating galaxy cluster masses from Chandra mock images. We utilize a Convolutional Neural Network (CNN), a deep machine learning tool…

The Califa and Hipass velocity function for all morphological galaxy types

S. Bekeraitė, C. J. Walcher, L. Wisotzki +17

The velocity function is a fundamental observable statistic of the galaxy population, similarly impor- tant as the luminosity function, but much more difficult to measure. In this…
