Wide Band Spectral and Timing Studies of Cosmic X-ray Sources
January 10-13, 2017 at TIFR-Mumbai, India

Wide band X-ray spectral and timing study of  Cosmic X-ray sources  has seen a tremendous boost in recent times due to the extension of focusing techniques to hard X-rays in NuSTAR and and the launch of Astrosat with a suite of instruments covering a wide X-ray range and also having a large area timing instrument.  This conference aims to bring together experts in this field and have an in-depth discussion on several of the emerging research topics like:

• Measuring the fundamental parameters of stellar mass black holes like mass and spin using X-ray spectral and timing studies. 
• Time resolved X-ray spectral study of pulsars (accreting as well as rotation powered pulsars).
• Cyclotron resonance features in accreting neutron stars.
• Accretion geometry in Cataclysmic Variables.
• Multi-wavelength studies of AGN.
• Disk-jet connection across mass scales. 
• Intermediate mass black holes.
• Hot astrophysical plasma.
