Methods for color center preserving hydrogen-termination of diamond

Daniel J. McCloskey, Daniel Roberts, Lila V. H. Rodgers +6

Chemical functionalization of diamond surfaces by hydrogen is an important method for controlling the charge state of near-surface fluorescent color centers, an essential process i…

Probing the co-evolution of SMBHs and their hosts from scaling relations pairwise residuals: dominance of stellar velocity dispersion and host halo mass

Francesco Shankar, Mariangela Bernardi, Daniel Roberts +17

The correlations between Supermassive Black Holes (SMBHs) and their host galaxies still defy our understanding from both the observational and theoretical perspectives. Here we per…

Shedding light on the star formation rate-halo accretion rate connection and halo quenching mechanism via DECODE, the Discrete statistical sEmi-empiriCal mODEl

Hao Fu, Lumen Boco, Francesco Shankar +9

Aims: The relative roles of the physical mechanisms involved in quenching galaxy star formation are still unclear. We tackle this fundamental problem with our cosmological semi-emp…

Semi-empirical Framework of Supermassive Black Hole Evolution: Highlighting a possible tension between Demographics and Gravitational Wave Background

Andrea Lapi, Francesco Shankar, Michele Bosi +4

The evolution of the supermassive Black Hole (BH) population across cosmic times remains a central unresolved issue in modern astrophysics, due to the many noticeable uncertainties…

Too many or too massive? Investigating the high- demography of active SMBHs from JWST

Daniel Roberts, Francesco Shankar, Vieri Cammelli +12

Recent JWST observations have unveiled a numerous population of low-luminosity active galactic nuclei (AGN) at , with space densities roughly an order of magnitude above p…

The role of black hole feedback on galaxy star formation and the degeneracy with halo quenching

Hao Fu, Francesco Shankar, Feng Yuan +9

The interplay between the accretion of supermassive black holes (SMBHs) and the stellar mass growth of the host galaxies is still a matter of hot debate. The accretion of the SMBHs…

Stellar streams from black hole-rich star clusters

Daniel Roberts, Mark Gieles, Denis Erkal +1

Nearly a hundred progenitor-less, thin stellar streams have been discovered in the Milky Way, thanks to Gaia and related surveys. Most streams are believed to have formed from star…

Formation of a boron-oxide termination for the (100) diamond surface

Alex K. Schenk, Rebecca Griffin, Anton Tadich +2

A boron-oxide termination of the diamond (100) surface has been formed by depositing molecular boron oxide onto the hydrogen-terminated (100) diamond surface under ul…

How galaxies acquire their stellar mass at high redshift: High star formation efficiencies and the relative roles of dust and initial mass function

Hao Fu, Francesco Shankar, Fabio Fontanot +9

JWST has measured an unprecedented abundance of galaxies above , whose formation and evolution are still difficult to reconcile within traditional galaxy evolution mo…
