By means of high resolution 2D hydrodynamical simulations, we study the evolution of the hot ISM for a large set of early-type galaxy models, characterized by various degrees of flattening and internal rotation. The galaxies are described by state-of-the-art axisymmetric two-component models, tailored to reproduce real systems; the dark matter haloes follow the Navarro-Frenk-White or the Einasto profile. The gas is produced by the evolving stars, and heated by Type Ia SNe. We find that, in… 
X-ray haloes and starformation in early-type galaxies
High resolution 2D hydrodynamical simulations describing the evolution of the hot ISM in state-of-the-art axisymmetric two-component models of early-type galaxies well reproduced the observed trends
The origin of the atomic and molecular gas contents of early-type galaxies - II. Misaligned gas accretion
We study the origin of the wide distribution of angles between the angular momenta of the stellar and gas components, αG, S, in early-type galaxies (ETGs). We use the GALFORM model of galaxy
AGN feedback and the origin and fate of the hot gas in early-type galaxies
A recent determination of the relationships between the X-ray luminosity of the ISM (Lx) and the stellar and total mass, for a sample of nearby early-type galaxies (ETGs), is used to investigate the
Cooling in the X-ray halo of the rotating, massive early-type galaxy NGC 7049
The relative importance of the physical processes shaping the thermodynamics of the hot gas permeating rotating, massive early-type galaxies is expected to be different from that in non-rotating
The Effect of the AGN Feedback on the Interstellar Medium of Early-Type Galaxies: 2D Hydrodynamical Simulations of the Low-Rotation Case
We present 2D hydrodynamical simulations for the evolution of early-type galaxies containing central massive black holes (MBHs), starting at age 2 Gyr. The code contains accurate and physically
AGN feedback and the origin and fate of the hot gas in early-type galaxies
Abstract We present the results of two-dimensional, grid-type hydrodynamical simulations, with parsec-scale central resolution, for the evolution of the hot gas in isolated early-type galaxies
Optically similar early-type galaxies are observed to have a large and poorly understood range in the amount of hot, X-ray-emitting gas they contain. To investigate the origin of this diversity, we
Metal abundances in the MACER simulations of the hot interstellar medium
A hot plasma is the dominant phase of the interstellar medium of early-type galaxies. Its origin can reside in stellar mass losses, residual gas from the formation epoch, and accretion from outside
Active Galactic Nucleus Feedback in an Elliptical Galaxy with the Most Updated AGN Physics. II. High Angular Momentum Case
We investigate the effects of AGN feedback on the cosmological evolution of an isolated elliptical galaxy by performing two-dimensional high-resolution hydrodynamical numerical simulations. The inner
What dominates the X-ray emission of normal galaxies?
Abstract X-ray surveys of normal galaxies, i.e. those that do not host actively supermassive black holes, have revealed important information on the nature of accreting stellar-mass compact objects


The effects of galaxy shape and rotation on the X-ray haloes of early-type galaxies
We present a detailed diagnostic study of the observed temperatures of the hot X-ray coronae of early-type galaxies. By extending the investigation carried out in Pellegrini (2011) with spherical
The effects of stellar dynamics on the X-ray emission of flat early-type galaxies
Observational and numerical studies gave hints that the hot gaseous haloes of ETGs may be sensitive to the galaxy internal kinematics. By using high resolution 2D hydro simulations, and realistic
The global energy budget of the hot gas flows in early-type galaxies is used to explain the recent observational results that S0 galaxies have lower mean X-ray luminosity $L_X$ per unit optical
Hot Gas Flows on Global and Nuclear Galactic Scales
Since its discovery as an X-ray source with the EinsteinObservatory, the hot X-ray emitting interstellar medium of early-type galaxies has been studied intensively, taking advantage of observations
Decoupled and Inhomogeneous Gas Flows in S0 Galaxies
A recent analysis of the Einstein sample of early-type galaxies has revealed that at any fixed optical luminosity LB, S0 galaxies have lower mean X-ray luminosity LX per unit LB than elliptical
Recently, the temperature T and the luminosity LX of the hot gas halos of early-type galaxies have been derived, with unprecedented accuracy, from Chandra data for a sample of 30 galaxies, covering a
Mass loss from evolved stars in elliptical galaxies
Most of the X-ray-emitting gas in early-type galaxies probably originates from red giant mass loss, and here we model the interaction between this stellar mass loss and the hot ambient medium. Using
The X-ray emission in post-merger ellipticals
The evolution in X–ray properties of early–type galaxies is largely unconstrained. In particular, little is known about how, and if, remnants of mergers generate hot gas halos. Here we examine the
AGN Feedback in Elliptical Galaxies: Numerical Simulations
The importance of feedback (radiative and mechanical) from massive black holes at the centers of elliptical galaxies is not in doubt, given the well established relation among black hole mass and

We make use of interferometric CO and HI observations, and optical integral-field spectroscopy from the ATLAS 3D survey to probe the origin of the molecular and ionised interstellar medium (ISM) in
