The long-term optical flux variations of Compact Symmetric Objects
Subhashree Swain, Vaidehi S. Paliya, D. J. Saikia +4
Compact Symmetric Objects (CSOs) are a distinct category of jetted active galactic nuclei (AGN) whose optical variability characteristics have not been well investigated. We presen…
Connections between Central Intensity Ratio and hot gas properties of early-type galaxies
K T Vinod, C Baheeja, C D Ravikumar
We report strong connections between central intensity ratio (CIR) and hot gas properties of Early-type galaxies (ETGs) in the nearby () Universe. We find new strong…
Study of central light distribution in nearby early-type galaxies hosting nuclear star clusters
K. Sruthi, C. D. Ravikumar
We present analysis of 63 nearby ( 44 Mpc) early-type galaxies hosting nuclear star clusters using the recently discovered parameter Central Intensity Ratio (CIR) determined…
Study of Central Intensity Ratio of Seyfert Galaxies in nearby Universe
K T Vinod, C Baheeja, S Aswathy +1
We use the recently discovered simple photometric parameter Central Intensity Ratio (CIR, Aswathy & Ravikumar 2018) determined for a sample of 57 nearby (z < 0.02) Seyfert galaxies…
Study of central intensity ratio of early-type galaxies from low density environment
K. Sruthi, C. D. Ravikumar
We present correlations involving central intensity ratio (CIR) of 52 early type galaxies, including 24 ellipticals and 28 lenticulars, selected from low density environment in the…
Co-evolution of Nuclear Rings, Bars and the Central Intensity Ratio of their Host Galaxies
S. Aswathy, C. D. Ravikumar
Using a sample of 13 early-type spiral galaxies hosting nuclear rings, we report remarkable correlations between the properties of the nuclear rings and the central intensity ratio…
