Tidal Disruption Events through the Lens of the Cooling Envelope Model

The Astrophysical Journal Letters
The cooling envelope model for tidal disruption events (TDEs) postulates that while the stellar debris streams rapidly dissipate their bulk kinetic energy (“circularize”), this does not necessarily imply rapid feeding of the supermassive black hole (SMBH)

Early identification of optical tidal disruption events

Astronomy & Astrophysics
Context. The detection of tidal disruption events (TDEs) is one of the key science goals of large optical time-domain surveys such as the Zwicky Transient Facility (ZTF) and the upcoming Vera C.

The IceShark, an effective method for sampling plankton under sea ice

Limnology and Oceanography: Methods, EarlyView.
Abstract Seasonal sea ice plays a crucial role in shaping coastal ecosystem dynamics throughout the circumpolar region. Of particular interest to oceanographers is the ice‐ocean interface which functions as a multidimensional habitat, supporting both sympagic algae and pelagic phytoplankton in the under‐ice surface waters.

Two‐Dimensional Transition Metal Dichalcogenides Properties Enhanced by Nano‐ and Micro‐Scale Shape Control

MetalMat, EarlyView.
This review explores current strategies for shaping two‐dimensional transition metal dichalcogenides (TMDs) beyond their planar form. It highlights how strain engineering, nanopatterning, and growth on complex substrates modulate their mechanical, optical, and electronic properties.

A New Population of Mid-infrared-selected Tidal Disruption Events: Implications for Tidal Disruption Event Rates and Host Galaxy Properties

The Astrophysical Journal
Most tidal disruption events (TDEs) are currently found in time-domain optical and soft X-ray surveys, both of which are prone to significant obscuration. The infrared (IR), however, is a powerful probe of dust-enshrouded environments; hence, we recently

Marine trophic architecture and hidden ecological connections in the Strait of Magellan: keystone species and ecosystem resilience

Oikos, EarlyView.
Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...

The effects of single versus successive warm summers on an intertidal community

Oikos, EarlyView.
To accurately predict how organisms and ecological communities will respond to future conditions caused by climate change, we must consider the temporal dynamics of environmental stressors, including the effects of repeated exposures to stress. We performed a two‐year passive thermal manipulation in coastal British Columbia, Canada to determine how ...
