... a matter of debate but the team have offered the suggestion that DRAGNS “may represent a rare phenomenon of elliptical galaxies transitioning back into spirals through accretion of gas and stars, perhaps from a companion.” Mulcahy and colleagues...
... an approximately ellipsoidal shape and a smooth, nearly featureless image. Stars found inside of elliptical galaxies are on average much older than stars found in spiral galaxies like our Milky Way. Despite what might appear as a now slow death...
... brighter in some bands than others. For example, spiral galaxies have a lot of young, blue stars so are brighter in some bands, whereas Elliptical galaxies have older, red stars, so are easier to see in other bands. Initially, we just used...
... detailed numerical simulations and predicted that this event may ultimately lead to the formation of one giant elliptical galaxy," said Paliya. "Depending on the physical conditions, it may host a relativistic jet, but that's in the distant future...
... to explain why there appears to be a shortfall in oxygen around elliptical rather than spiral galaxies, as highlighted by puzzling COS observations. "The CGM of the elliptical galaxies is hotter," said Joop Schaye, a professor at Leiden University...
... the speed of carbon monoxide gas swirling around the black hole at the centre of NGC 1332, a massive elliptical galaxy in the direction of the southern constellation Eridanus. "Measuring the mass of a black hole accurately is very challenging, even...
