Semi‐Volatile Organic Partitioning Improves Simulation of Biomass Burning Aerosol Mixing State Evolution

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Biomass burning aerosols significantly contribute to atmospheric composition and radiative forcing, with black carbon (BC) mixing states critically influencing optical properties and climate impacts. Recent field observations reveal a systematic three‐phase evolution in BC coating thickness during plume aging: rapid initial growth, quasi ...

On Error Estimates for Hapke Photometric Model Parameters from Disk-integrated Phase Curves of Airless Planetary Bodies

The Planetary Science Journal
The Hapke bidirectional reflectance model is widely used to analyze photometric observations of planetary surfaces. When fitting disk-integrated data, nonuniqueness concerns arise if observations lack sufficient phase angle coverage to constrain the ...

Unlocking AGN variability with custom ZTF photometry for high-fidelity light curves and robust selection

Astronomy & Astrophysics
Aims. We explored the potential of optical variability selection methods in order to identify a broad range of active galactic nuclei (AGN), including those challenging to detect with conventional techniques. Using the unprecedented combination of depth,

A Highly Magnetic Ultramassive White Dwarf with a 23 minute Rotation Period

The Astrophysical Journal
We present a physical characterization of Tsinghua University-Ma Huateng Telescope for Survey (TMTS) J00063798+3104160 (J0006), a rapidly rotating, ultramassive white dwarf (WD) identified in high-cadence light curves from the TMTS.

Multiple Emission Lines of Hα Emitters at z ∼ 2.3 from the Broad- and Medium-band Photometry in the ZFOURGE Survey

The Astrophysical Journal
We present a multiple emission line study of ∼1300 H α emitters (HAEs) at z ∼ 2.3 in the ZFOURGE survey. In contrast to the traditional spectroscopic method, our sample is selected based on the flux excess in the ZFOURGE K _s broadband data relative to ...

Exploring Quasar Variability with ZTF at 0 < z < 3: A Universal Relation with the Eddington Ratio

The Astrophysical Journal
Quasars, powered by accretion onto supermassive black holes (SMBHs), exhibit significant variability, offering insights into the physics of accretion and the properties of the central engines.
