Librational Feedback Cooling

Kavli Affiliate: Giorgio Gratta | First 5 Authors: Charles P. Blakemore, Denzal Martin, Alexander Fieguth, Nadav Priel, Gautam Venugopalan | Summary: Librational motion, whereby a rigid body undergoes angular oscillation around a preferred direction, can be observed in optically trapped, silica microspheres. We demonstrate the cooling of one librational degree of freedom for $sim 5~mu$m […]

Accretion Variability as a Guide to Stellar Mass Assembly

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: William J. Fischer, Lynne A. Hillenbrand, Gregory J. Herczeg, Doug Johnstone, Ágnes Kóspál | Summary: Variable accretion in young stellar objects reveals itself photometrically and spectroscopically over a continuum of timescales and amplitudes. Most dramatic are the large outbursts (e.g., FU Ori, V1647 Ori, and EX […]

Active control of thermal emission by graphene-nanowire coupled plasmonic metasurfaces

Kavli Affiliate: Zhuo Li | First 5 Authors: Jiayu Li, Zhuo Li, Xiu Liu, Stanislav Maslovski, Sheng Shen | Summary: Metasurfaces, together with graphene plasmonics, have become prominent for the emissivity control in thermal engineering, both passively through changing the geometric parameters and packing density of the metasurfaces, and actively through graphene gating or doping. […]

On the Connection between Supermassive Black Hole and Galaxy Growth in the Reionization Epoch

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Junyao Li, John D. Silverman, Takuma Izumi, Wanqiu He, Masayuki Akiyama | Summary: The correlation between the mass of supermassive black holes (SMBHs; $mathcal{M}_{rm BH}$) and their host galaxies ($mathcal{M}_star$) in the reionization epoch provides valuable constraints on how their growth are jointly assembled in the early […]

Absorption Variability of the Highly Obscured Active Galactic Nucleus NGC 4507

Kavli Affiliate: Claudio Ricci | First 5 Authors: Arghajit Jana, Claudio Ricci, Sachindra Naik, Atsushi Tanimoto, Neeraj Kumari | Summary: We present a detailed study of the highly obscured active galaxy NGC 4507, performed using four Nuclear Spectroscopic Telescope Array (NuSTAR) observations carried out between May and August in 2015 (~ 130 ks in total). […]

Galactic angular momentum in the IllustrisTNG simulation — I. Connection to morphology, halo spin, and black hole mass

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Vicente Rodriguez-Gomez, Shy Genel, S. Michael Fall, Annalisa Pillepich, Marc Huertas-Company | Summary: We use the TNG100 simulation of the IllustrisTNG project to investigate the stellar specific angular momenta ($j_{ast}$) of $sim$12~000 central galaxies at $z=0$ in a full cosmological context, with stellar masses ($M_{ast}$) ranging from […]

Advancing the Landscape of Multimessenger Science in the Next Decade

Kavli Affiliate: Nicola Omodei | First 5 Authors: Kristi Engel, Tiffany Lewis, Marco Stein Muzio, Tonia M. Venters, Markus Ahlers | Summary: The last decade has brought about a profound transformation in multimessenger science. Ten years ago, facilities had been built or were under construction that would eventually discover the nature of objects in our […]
