Density distribution of the cosmological matter field
The one-point probability distribution function (PDF) of the matter density field in the universe is a fundamental property that plays an essential role in...
Density weighted angular redshift fluctuations: a new cosmological observable
We propose the use of angular fluctuations in the galaxy redshift field as a new way to extract cosmological information in the Universe. This new probe $\delta...
DESI Early Data Release Milky Way Survey value-added catalogue
We present the stellar value-added catalogue based on the Dark Energy Spectroscopic Instrument (DESI) Early Data Release. The catalogue contains radial velocity...
Detailed chemical evolution models of the Tucana dSph galaxy
We use semi-analytical methods to obtain detailed chemical evolution models (CEMs) for the dwarf spheroidal (dSph) galaxy Tucana. Published star formation rates...
Detailed spectrophotometric analysis of the superluminous and fast evolving SN 2019neq
SN 2019neq was a very fast evolving superluminous supernova. At a redshift z = 0.1059, its peak absolute magnitude was -21.5 ± 0.2 mag in g band. In this work...
Detailed study of the microwave emission of the supernova remnant 3C 396
We have observed the supernova remnant 3C 396 in the microwave region using the Parkes 64-m telescope. Observations have been made at 8.4, 13.5, and 18.6 GHz...
Detecting faint secondaries of spectroscopic binaries: HD 101177B and 149414A
We have observed HD 101177B and 149414A, two known single-lined binaries, and directly measured the radial velocities of their secondaries, enabling us to...
Detecting microvariability in type 2 quasars using enhanced F-test
Microvariability (intranight variability) is a low amplitude flux change at short time-scales (i.e. hours). It has been detected in unobscured type 1 active...
Detecting outliers in astronomical images with deep generative networks
With the advent of future big-data surveys, automated tools for unsupervised discovery are becoming ever more necessary. In this work, we explore the ability of...
