Overdense fireworks in GOODS-N: Unveiling a record number of massive dusty star-forming galaxies at z ∼ 5.2 with the N2CLS

Astronomy & Astrophysics
High-density environments, such as early galaxy overdensities, play a critical role in hierarchical structure formation and galaxy evolution, providing an ideal setting for accelerated galaxy growth. The GOODS-N overdensity at z ≃ 5.2 has long been known,

Cowbirds use conspecific social information to detect host nests in the wild

Ibis, EarlyView.
Recent work shows that hosts of avian brood parasites use social information to increase egg rejection rates, but fewer studies explore how parasites themselves use such information to detect host nests in the wild. To determine whether wild Brown‐headed Cowbirds Molothrus ater use social information to detect host nests, we measured how individual ...

FEAST: JWST/NIRCam View of the Resolved Stellar Populations of the Interacting Dwarf Galaxies NGC 4485 and NGC 4490

The Astrophysical Journal
We present new JWST/NIRCam observations of the interacting dwarf galaxy system NGC 4485–NGC 4490 (aka Arp 269), obtained as part of the Cycle 1 Feedback in Emerging Extragalactic Star Clusters (FEAST) program. NGC 4485 and NGC 4490 form the closest known

Kinematic and extinction analysis of a potential spiral arm beyond the Galactic bar

Astronomy & Astrophysics
Context. Determining the structure of the Milky Way is essential for understanding its morphology, dynamics, and evolution. However, studying its innermost regions is challenging due to high extinction and crowding.

How Important Is the Home Market for Cross‐Listed Biotech Companies?

International Finance, EarlyView.
ABSTRACT This study investigates five German biotechnology firms cross‐listed on XETRA and NASDAQ. By employing high‐frequency data, we estimate both bivariate and trivariate vector error correction models—the latter explicitly accounting for exchange rate dynamics—to assess which market, domestic or U.S., leads in price discovery.

Testing a New Star Formation History Model from Principal Component Analysis to Facilitate Spectral Synthesis Modeling

The Astrophysical Journal
The spectrum of a galaxy is a complicated convolution of many properties of the galaxy, such as the star formation history (SFH), initial mass function, and metallicity.

Innovation Diffusion Among Case‐Based Decision‐Makers

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT This paper analyzes a model of innovation diffusion with case‐based individuals a la Gilboa and Schmeidler, who decide whether to consume an incumbent or a new product based on their and their social neighbors' previous consumption experiences. I analyze how diffusion patterns change with individual characteristics, innovation characteristics,

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

Women Directors and R&D Investment in Family Firms: The Mediating Role of Debt Financing

Journal of Product Innovation Management, EarlyView.
ABSTRACT Although research examining the role of women directors in fostering innovation within family firms continues to expand, the mechanisms underlying their influence remain insufficiently understood. This study examines the mediating role of debt financing in the relationship between women directors and R&D investment.

Total and dark mass from observations of galaxy centers with machine learning

Astronomy & Astrophysics
Context. The galaxy total mass inside the effective radius is a proxy of the galaxy dark matter content and the star formation efficiency. As such, it encodes important information on the dark matter and baryonic physics. Aims.
