Powering galactic super-winds with small-scale AGN winds
Tiago Costa, Rüdiger Pakmor, Volker Springel
We present a new implementation for active galactic nucleus (AGN) feedback through small-scale, ultra-fast winds in the moving-mesh hydrodynamic code AREPO. The wind is injected by…
The REQUIEM Survey I: A Search for Extended Ly-Alpha Nebular Emission Around 31 z>5.7 Quasars
Emanuele Paolo Farina, Fabrizio Arrigoni-Battaia, Tiago Costa +19
The discovery of quasars few hundred megayears after the Big Bang represents a major challenge to our understanding of black holes and galaxy formation and evolution. Their luminos…
The hidden satellites of massive galaxies and quasars at high-redshift
Tiago Costa, Joakim Rosdahl, Taysun Kimm
Using cosmological, radiation-hydrodynamic simulations targeting a rare halo at , we show that the number counts and inter…
Cold Molecular Outflows in the Local Universe
A. Fluetsch, R. Maiolino, S. Carniani +7
We study molecular outflows in a sample of 45 local galaxies, both star forming and AGN, primarily by using CO data from the ALMA archive and from the literature. For a subsample w…
AGN outflows and feedback twenty years on
C. M. Harrison, T. Costa, C. N. Tadhunter +4
It is the twentieth anniversary of the publication of the seminal papers by Magorrian et al. and Silk & Rees which, along with other related work, ignited an explosion of publicati…
The 500 ks Chandra observation of the z = 6.31 QSO SDSS J1030+0524
R. Nanni, R. Gilli, C. Vignali +23
We present the results from a ks Chandra observation of the QSO SDSS J1030+0524. This is the deepest X-ray observation to date of a QSO. The QSO is dete…
