A practical guide to the massive black hole cosmic history [PDF]

, 2011
I review our current understanding of massive black hole (MBH) formation and evolution along the cosmic history. After a brief introductory overview of the relevance of MBHs in the hierarchical structure formation paradigm, I discuss the main viable ...

Assessing how restoration can facilitate 30×30 goals for climate‐resilient coastal ecosystems in the United States

Conservation Biology, Volume 39, Issue 3, June 2025.
Abstract Ecosystems globally have reached critical tipping points because of climate change, urbanization, unsustainable resource consumption, and pollution. In response, international agreements have set targets for conserving 30% of global ecosystems and restoring 30% of degraded lands and waters by 2030 (30×30).

Toward precise constraints on growth of massive black holes

, 2008
Growth of massive black holes (MBHs) in galactic centers comes mainly from gas accretion during their QSO/AGN phases. In this paper we apply an extended Soltan argument, connecting the local MBH mass function with the time-integral of the QSO luminosity ...

Adherence in Rheumatoid Arthritis patients assessed with a validated Italian version of the 5-item compliance questionnaire for rheumatology [PDF]

, 2019
OBJECTIVES: The 5-item Compliance Questionnaire for Rheumatology (CQR5) proved reliability and validity in respect of identification of patients likely to be high adherers (HAs) to anti-rheumatic treatment, or low adherers (LAs), i.e ...

Efficient Merger of Binary Supermassive Black Holes in Merging Galaxies

, 2011
In spherical galaxies, binary supermassive black holes (SMBHs) have difficulty reaching sub-parsec separations due to depletion of stars on orbits that intersect the massive binary - the final-parsec problem.

Staging the ‘Forgotten Genocide’ in the Aftermath of the Dirty War: Una bestia en la luna by Richard Kalinoski [PDF]

, 2015
The most recent Argentine military dictatorship (1976-1983) and the Armenian Genocide (1915-1923) share legacies of state-sanctioned denial and impunity, which have left survivors and subsequent generations grappling with issues of memory and mourning ...

Dynamics around supermassive black holes

, 2007
The dynamics of galactic nuclei reflects the presence of supermassive black holes (SBHs) in many ways. Single SBHs act as sinks, destroying a mass in stars equal to their own mass in roughly one relaxation time and forcing nuclei to expand.

Prompt Tidal Disruption of Stars as an Electromagnetic Signature of Supermassive Black Hole Coalescence

, 2010
A precise electromagnetic measurement of the sky coordinates and redshift of a coalescing black hole binary holds the key for using its gravitational wave (GW) signal to constrain cosmological parameters and to test general relativity.

Massive Binary Black Holes in the Cosmic Landscape

, 2009
Binary black holes occupy a special place in our quest for understanding the evolution of galaxies along cosmic history. If massive black holes grow at the center of (pre-)galactic structures that experience a sequence of merger episodes, then dual black
