Fractal Aggregates of Submicron-sized Grains in the Young Planet-forming Disk around IM Lup
The Astrophysical Journal Letters, 2023 Despite rapidly growing disk observations, it remains a mystery what primordial dust aggregates look like and what the physical and chemical properties of their constituent grains (monomers) are in young planet-forming disks. Confrontation of models with

An updated measurement of the Hubble constant from near-infrared observations of Type Ia supernovae [PDF]
Astronomy & Astrophysics, 2022 We present a measurement of the Hubble constant ($H_0$) using type Ia supernova (SNe Ia) in the near-infrared (NIR) from the recently updated sample of SNe Ia in nearby galaxies with distances measured via Cepheid period-luminosity relations by the SHOES
