About one in 10 elliptical galaxies contain disks of cold molecular gas and dust that orbit their centers.
For a precise measurement, we need to zoom in to the very centre of a galaxy where the black hole’s gravitational pull is the dominant force. ALMA is a fantastic new tool for carrying out these observations.observes the wavelength at which the molecules glow brightly.NGC 1332 is a giant elliptical galaxy in the southern sky 73 million light-years from Earth. The scientist explained,About one in 10 elliptical galaxies contain disks of cold molecular gas and dust that orbit their centers.
Super-massive black hole is 660 millions of the sun
This is among the most precise measurements
We are directly viewing the region where the cold gas
Colder molecules always emit lights around black hole
Super massive black hole is present around galaxy
Doppler effect is a change in the frequency of sound or light
The emissions caused due to CO molecules are usually bright
