Near-infrared bulge-disc correlations of lenticular galaxies
Sudhanshu Barway, Yogesh Wadadekar, Ajit K. Kembhavi +1
We consider the luminosity and environmental dependence of structural parameters of lenticular galaxies in the near-infrared K band. Using a two-dimensional galaxy image decomposit…
Properties of warm absorbers in active galaxies: a systematic stability curve analysis
Susmita Chakravorty, Ajit K. Kembhavi, Martin Elvis +1
Signatures of warm absorbers are seen in soft X-ray spectra of about half of all Seyfert1 galaxies observed and in some quasars and blazars. We use the thermal equilibrium curve to…
Images IV: Strong evolution of the oxygen abundance in gaseous phases of intermediate mass galaxies since z=0.8
M. Rodrigues, F. Hammer, H. Flores +22
Intermediate mass galaxies (logM(Msun)>10) at z~0.6 are the likeliest progenitors of the present-day numerous population of spirals. There is growing evidence that they have evolve…
Towards a robust estimate of the merger rate evolution using near-IR photometry
A. Rawat, Francois Hammer, Ajit K. Kembhavi +1
We use a combination of deep, high angular resolution imaging data from the CDFS (HST/ACS GOODS survey) and ground based near-IR images to derive the evolution of the galaxy…
Dielectronic recombination and stability of warm gas in AGN
Susmita Chakravorty, Ajit K. Kembhavi, Martin Elvis +2
Understanding the thermal equilibrium (stability) curve may offer insights into the nature of the warm absorbers often found in active galactic nuclei. Its shape is determined by f…
Unravelling the morphologies of Luminous Compact Galaxies using the HST/ACS GOODS survey
A. Rawat, A. K. Kembhavi, F. Hammer +2
(Abridged) Luminous Compact Galaxies (LCGs) (M_B < -20, R_{1/2} < 4.5kpc and EW_{0}(OII) >15Å) constitute one of the most rapidly evolving galaxy populations over the last ~8 Gyr h…
