Identifier: http://hdl.handle.net/1959.14/297908
Description: NGC 1266 is a nearby field galaxy observed as part of the ATLAS 3D survey (Cappellari et al. 2011). NGC 1266 has been shown to host a compact (< 200 pc) molecular disk and a mass-loaded molecular outf ... More

Identifier: http://hdl.handle.net/1959.14/297872
Description: According to a popular scenario supported by numerical models, the mass assembly and growth of massive galaxies, in particular the Early-Type Galaxies (ETGs), is, below a redshift of 1, mainly due to ... More

Identifier: http://hdl.handle.net/1959.14/297851
Description: Recently, massive early-type galaxies have shed their red-and-dead moniker, thanks to the discovery that many host residual star formation. As part of the ATLAS-3D project, we have conducted a complet ... More

Identifier: http://hdl.handle.net/1959.14/298092
Description: Much of our knowledge of galaxies comes from analysing the radiation emitted by their stars, which depends on the present number of each type of star in the galaxy. The present number depends on the s ... More

Identifier: http://hdl.handle.net/1959.14/298375
Description: We report the discovery of a powerful molecular wind from the nucleus of the non-interacting nearby S0 field galaxy NGC 1266. The single-dish CO profile exhibits emission to ±400kms⁻¹ and requires a n ... More

Identifier: http://hdl.handle.net/1959.14/300329
Description: We propose a simple model for the origin of fast and slow rotator early-type galaxies (ETG) within the hierarchical ⋀cold dark matter (⋀CDM) scenario, that is based on the assumption that the mass fra ... More

Identifier: http://hdl.handle.net/1959.14/298590
Description: The mass assembly of galaxies leaves various imprints on their surroundings, such as shells, streams and tidal tails. The frequency and properties of these fine structures depend on the mechanism driv ... More
