SN 2022oqm: A Bright and Multipeaked Calcium-rich Transient

The Astrophysical Journal
We present the photometric and spectroscopic evolution of SN 2022oqm, a nearby multipeaked hydrogen- and helium-weak calcium-rich transient (CaRT). SN 2022oqm was detected 13.1 kpc from its host galaxy, the face-on spiral galaxy NGC 5875.

Novel Atmospheric Dynamics Shape the Inner Edge of the Habitable Zone around White Dwarfs

The Astrophysical Journal
White dwarfs offer a unique opportunity to search nearby stellar systems for signs of life, but the habitable zone around these stars is still poorly understood.

Evaluation of Brain Microstructural Alterations in Preschool Autism Spectrum Disorder: A Voxel‐Wise Multimodal MRI Study

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Autism Spectrum Disorder (ASD) presents with early neurodevelopmental alterations in preschool children, yet comprehensive characterization using multimodal quantitative MRI remains limited in this age group. Purpose To investigate voxel‐wise brain microstructural differences in preschool ASD through integrated analysis of cerebral ...

Geochronology of the Whittlesey sedimentary succession, eastern England: The ‘Pompeii’ of the British late Middle Pleistocene to Holocene record

Journal of Quaternary Science, EarlyView.
Abstract The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...

The Evolution of Hypervelocity Supernova Survivors and the Outcomes of Interacting Double White Dwarf Binaries

The Astrophysical Journal
The recent prediction and discovery of hypervelocity supernova survivors has provided strong evidence that the “dynamically driven double-degenerate double-detonation” (D ^6 ) Type Ia supernova scenario occurs in nature.
