Published in 2021 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stab536

Abstract: We investigate the internal structure of elliptical galaxies at $z\sim 0.2$ from a joint lensing-dynamics analysis. We model Hubble Space Telescope images of a sample of 23 galaxy-galaxy lenses selected from the Sloan Lens ACS… read more here.

Published in 2023 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stad1124

Abstract: One of the most protracted problems in astronomy has been understanding the evolution of galaxy morphology. Much discussion has surrounded how lenticular galaxies may form a bridging population between elliptical and spiral galaxies. However, with… read more here.

Published in 2017 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stx2030

Abstract: We present significantly improved measurements of turbulent velocities in the hot gaseous haloes of nearby giant elliptical galaxies. Using deep XMM-Newton Reflection Grating Spectrometer (RGS) observations and a combination of resonance scattering and direct line… read more here.

Published in 2018 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stx2442

Abstract: In order to investigate the formation mechanisms of the rare compact elliptical galaxies (cE) we have compiled a sample of 25 cEs with good SDSS spectra, covering a range of stellar masses, sizes and environments.… read more here.

Published in 2018 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stx3254

Abstract: We determine abundance ratios of 37 dwarf ellipticals (dEs) in the nearby Virgo cluster. This sample is representative of the early-type population of galaxies in the absolute magnitude range -19.0 read more here.

Published in 2019 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stz3068

Abstract: We use high-resolution hydrodynamical simulations run with the EAGLE model of galaxy formation to study the differences between the properties of – and subsequently the lensing signal from – subhaloes of massive elliptical galaxies at… read more here.

Published in 2017 at "Physical Review D"

DOI: 10.1103/physrevd.95.063020

Abstract: After thirty years of the discovery of the fundamental plane, explanations to the tilt of the fundamental plane with respect to the virial plane still suffer from the need of fine-tuning. In this paper, we… read more here.

Published in 2022 at "Sains Malaysiana"

DOI: 10.17576/jsm-2022-5109-25

Abstract: We investigated the star formation rates (SFRs) of selected elliptical galaxies using the infrared data from the Wide-field Infrared Survey Explorer (WISE). The elliptical galaxies were selected from the Sloan Digital Sky Survey (SDSS) MPA-JHU… read more here.
