Spectroscopic and photometric confirmation of 3 globular and 14 intermediate-age clusters in the Irr II galaxy NGC3077
Pedro A. Ovando Ramirez, Y. D. Mayya, Lino H. Rodriguez-Merino +4
We present the results from spectroscopic and photometric analysis of 17 globular cluster (GC) candidates in the Irr II galaxy NGC 3077. The GC candidates were selected on the Hubb…
