The Atacama Cosmology Telescope: Passband Measurements with an Analysis of Systematic Errors

Kavli Affiliate: Jeffrey McMahon | Summary:We present measurements of the spectral response of the four Advanced ACTPol (AdvACT) multichroic detector arrays, which observed in frequency bands centered near 30, 40, 90, 150, and 220 GHz. The passbands were measured with a Fourier transform spectrometer (FTS) combined with coupling optics that direct and match the output […]

ATG2A interacts with RAB1A and ARFGAP1 positive membranes during autophagosome biogenesis

Kavli Affiliate: Pietro De Camilli | Authors: Devin M Fuller, Yumei Wu, Florian Schueder, Burha Rasool, Shanta Nag, Justin L. Korfhage, Rolando Garcia-Milian, Katerina D Melnyk, Joerg Bewersdorf, Pietro De Camilli and Thomas Melia | Summary: Autophagosomes form from seed membranes that expand through bulk-lipid transport via the bridge-like lipid transporter ATG2. The origins of […]

Observation of magnetic quantum phase crossovers in a semiconductor spin ladder

Kavli Affiliate: Menno Veldhorst | Summary:Understanding collective phases of strongly correlated quantum magnets relies on theoretically tractable model systems with precise microscopic control. Antiferromagnetic spin ladders provide such a setting, hosting field-tunable gapped and gapless phases at half filling and unconventional pairing tendencies upon doping. Here, we realize a programmable Heisenberg spin ladder in a […]

The VariableTNG project: how baryonic mechanisms shape galaxy properties

Kavli Affiliate: Luis Ho | Summary:We use 50 Sobol-sampled VariableTNG simulations, varying eight subgrid parameters at fixed cosmology and initial conditions, to determine which baryonic processes regulate galaxies and black holes at $z=6$ and $z=8$. We compare the simulations with recent high-redshift measurements of the stellar mass function, star-forming main sequence, stellar and gas-phase mass-metallicity […]
