ABSTRACT We include a fully coupled treatment of metal and dust enrichment into the Delphi semi-analytic model galaxy formation to explain content 13 Lyman break galaxies (LBGs) detected by Atacama Large millimetre Array (ALMA) REBELS Program at z ≃ 7. find that mass, Md, is regulated combination Type II supernova production, astration, shock destruction, ejection in outflows; grain growth (with standard time-scale τ0 = 30 Myr) plays negligible role. The predicts dust-to-stellar mass ratio...
The CERN Axion Solar Telescope (CAST) searches for $a\ensuremath{\rightarrow}\ensuremath{\gamma}$ conversion in the 9 T magnetic field of a refurbished LHC test magnet that can be directed toward Sun. Two parallel bores filled with helium adjustable pressure to match x-ray refractive mass ${m}_{\ensuremath{\gamma}}$ axion search ${m}_{a}$. After vacuum phase (2003--2004), which is optimal ${m}_{a}\ensuremath{\lesssim}0.02\text{ }\text{ }\mathrm{eV}$, we used $^{4}\mathrm{He}$ 2005--2007...
We couple the DELPHI framework for galaxy formation with a model escape of ionizing photons to study both its variability assembly and resulting key reionization sources. In this model, leakage either occurs through fully ionized gas distribution (ionization bounded) or additionally channels cleared by supernova explosions bounded + holes). The fraction is therefore governed combination density star rate. Having calibrated our efficiencies match high-$z$ observables, we find central regulate...
Context. Mid-IR water lines from protoplanetary disks around T Tauri stars have a detection rate of 50%. Models identified multiple physical properties such as dust-to-gas mass ratio, dust size power law distribution, disk gas mass, inner radius, and scale height potential explanations for the current rate.
The goal of the AEgIS experiment is to measure gravitational acceleration antihydrogen – simplest atom consisting entirely antimatter with ultimate precision 1%. We plan verify Weak Equivalence Principle (WEP), one fundamental laws nature, an beam. consists a positron accumulator, antiproton trap and Stark accelerator in solenoidal magnetic field form accelerate pulsed beam atoms towards free-fall detector. passes through moiré deflectometer vertical displacement due force. A position time...
We focus on exploring the metal enrichment of intergalactic medium (IGM) in Cold and Warm (1.5 3 keV) Dark Matter (DM) cosmologies, constraints this yields DM particle mass, using a semi-analytic model, Delphi, that jointly tracks baryonic assembly galaxies at $z \simeq 4-20$ including both Supernova (a range of) reionization feedback (models). find while ${\rm M_{UV}} \geq -15$ contribute half all IGM metals model by 4.5$, given suppression low-mass halos, larger halos with \leq provide...
