  • S7 : Probing the physics of seyfert galaxies through their ENLR & HII regions 
    Dopita, M. A; Shastri, P; Scharwachter, J; Kewley, L. J; Davies, R; Sutherland, R; Kharb, P; Jose, Jessy; Bhatt, H. C; Ramya, S; Hamptona, E; Jina, C; Banfielda, J; Zawa, I; Srivastavaa, Shweta; Jamesa, B (Cambridge University Press, 2015-02)
    Here we present the first results from the Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7) which aims to investigate the physics of ∼140 radio-detected southern active Galaxies with z<0.02 through Integral ...
  • The sharpest ultraviolet view of the star formation in an extreme environment of the nearest Jellyfish Galaxy IC 3418 
    Hota, Ananda; Devaraj, A; Pradhan, A. C; Stalin, C. S; George, Koshy; Mohapatra, Abhisek; Rey, Soo-Chang; Ohyama, Youichi; Vaddi, Sravani; Pechetti, Renuka; Ramya, S; Jose, Jessy; Roy, Jayashree; Konar, Chiranjib (Indian Academy of Sciences, 2021-10)
    We present the far ultraviolet (FUV) imaging of the nearest Jellyfish or Fireball galaxy IC3418/VCC 1217, in the Virgo cluster of galaxies, using Ultraviolet Imaging Telescope (UVIT) onboard the AstroSat satellite. The ...
  • Star formation in blue compact dwarf Galaxies 
    Ramya, S; Prabhu, T. P; Sahu, D. K (Astronomical Society of India, 2012)
    Blue compact dwarf galaxies (BCDGs) are dwarfs undergoing current burst of star formation (SF). In our work, we determine the ages of the underlying old stellar population to be ∼4 Gyr that is dominating the mass of the ...
  • Star formation in blue compact dwarf galaxies: Mkn 104 and I Zw 97 
    Ramya, S; Sahu, D. K; Prabhu, T. P (Blackwell Publishing, 2009-06)
    Two blue compact dwarf galaxies, Mkn 104 and I Zw 97, are studied photometrically and spectroscopically. Mkn 104 is found to contain three distinct bright star-forming regions, whereas I Zw 97 is found to contain three ...
  • Star formation in bulgeless late type spiral Galaxies 
    Das, M; Ramya, S; Sengupta, C; Mishra, K (Astronomical Society of India, 2012)
    We present radio and follow-up optical observations of a sample of bulgeless late type spiral galaxies. We searched for signs of nuclear activity and disk star formation in the sample galaxies. Interaction induced star ...
  • Star formation in bulgeless late-type galaxies: clues to their evolution 
    Mousumi Das; Sengupta, C; Ramya, S; Misra, K (Wiley-Blackwell, 2012-07)
    We present Giant Meterwave Radio Telescope 1280-MHz radio continuum observations and follow-up optical studies of the disc and nuclear star formation in a sample of low-luminosity bulgeless galaxies. The main aim is to ...
  • Study of star formation in NGC 1084 
    Ramya, S; Sahu, D. K; Prabhu, T. P (Blackwell Publishing, 2007-10)
    We present UBVRI broad-band, Hα narrow-band photometry of the star-forming complexes in the infrared bright galaxy NGC 1084. Results of medium-resolution spectroscopy of some of the brighter complexes are also discussed. ...
