Exploring Lenticular Galaxy Formation in Field Environments Using NewHorizon: Evidence for Counterrotating Gas Accretion as a Formation Channel

The Astrophysical Journal
The formation pathways of lenticular galaxies (S0s) in field environments remain a matter of debate. We utilize the cosmological hydrodynamic simulation, NewHorizon , to investigate the issue. We select two massive star formation quenched S0s as our main

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK

Journal of Research in Science Teaching, EarlyView.
ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).

CEERS Key Paper. IX. Identifying Galaxy Mergers in CEERS NIRCam Images Using Random Forests and Convolutional Neural Networks

The Astrophysical Journal Letters
A crucial yet challenging task in galaxy evolution studies is the identification of distant merging galaxies, a task that suffers from a variety of issues ranging from telescope sensitivities and limitations to the inherently chaotic morphologies of ...

Composition of White Rhinoceros Colostrum and Changes During Early Lactation to Mature Milk

Zoo Biology, EarlyView.
The colostrum phase of white rhinoceros milk ends after 2 days of lactation. The mature milk phase commences after 5 days. The fat content peaks at days 3–4. The Δ9‐desaturase 16 and ‐18 indexes peak at days 2–3. ABSTRACT The proximate composition of milk from seven free‐ranging white rhinoceroses during the first 20 days of lactation is reported with ...

Where Have All the Little Red Dots Gone? Supermassive Black Hole Binary Dynamics and Its Impact on Galaxy Properties

The Astrophysical Journal Letters
Recent James Webb Space Telescope observations have revealed a peculiar class of galaxies at redshifts z  ≳ 6, characterized by extremely high central stellar densities and overmassive central supermassive black holes (SMBHs), “little red dots” (LRDs). A

Globular cluster systems as clues to galaxy evolution [PDF]

We investigate the properties of systems of globular clusters in light of the hypothesis that galaxy mergers play a major role in galaxy evolution. In a previous paper, we presented a model in which the formation of globular clusters occurs during galaxy

From cities to refuges for pollinators: Urban practices for enhancing pollinator habitats in changing landscapes

Journal of Applied Ecology, EarlyView.
A framework for the support of pollinators in urban areas is developed here, based on five pillars: nesting, flower resources, artificial support, management and society acceptance, with additional key elements from science and society. Society should incorporate strategies for pollinators as in this framework by means of co‐planning with stakeholders,
