Luminosity Functions of Spitzer Identified Protostars in Nine Nearby Molecular Clouds

, 2012
We identify protostars in Spitzer surveys of nine star-forming molecular clouds within 1 kpc: Serpens, Perseus, Ophiuchus, Chamaeleon, Lupus, Taurus, Orion, Cep OB3, and Mon R2, which combined host over 700 protostar candidates.

Compact Spectral Imaging: A Review of Miniaturized and Integrated Systems

Laser &Photonics Reviews, Volume 19, Issue 21, November 6, 2025.
This review explores the rapid shift toward compact spectral imaging systems by examining four key design paradigms: Do‐It‐Yourself (DIY) platforms, freeform optics, filter‐on‐chip integration, and multifunctional metasurfaces. The discussion highlights critical applications in medicine, agriculture, and environmental monitoring, providing comparative ...

Thermal Infrared Spectrometers for the Polar Radiant Energy in the Far‐Infrared Experiment (PREFIRE)

Earth and Space Science, Volume 12, Issue 10, October 2025.
Abstract The Polar Radiant Energy in the Far‐InfraRed Experiment (PREFIRE) was selected by NASA to fly two miniaturized Thermal InfraRed Spectrometers (TIRS) capable of distinguishing the spectral signatures of surface and atmospheric properties in Earth's polar regions.

CASTRO: A New Compressible Astrophysical Solver. III. Multigroup Radiation Hydrodynamics

, 2012
We present a formulation for multigroup radiation hydrodynamics that is correct to order $O(v/c)$ using the comoving-frame approach and the flux-limited diffusion approximation. We describe a numerical algorithm for solving the system, implemented in the

Radiation Magnetohydrodynamics Simulation of Proto-Stellar Collapse: Two-Component Molecular Outflow

, 2010
We perform a three-dimensional nested-grid radiation magneto-hydrodynamics (RMHD) simulation with self-gravity to study the early phase of the low-mass star formation process from a rotating molecular cloud core to a first adiabatic core just before the ...

Does feedback help or hinder star formation? The effect of photoionisation on star formation in Giant Molecular Clouds [PDF]

, 2016
We investigated the effect of photoionising feedback inside turbulent star-forming clouds, comparing the resultant star formation in both idealised profiles and more realistic cloud structures drawn from a global galaxy simulation.

Disruption of giant molecular clouds and formation of bound star clusters under the influence of momentum stellar feedback

, 2019
Energetic feedback from star clusters plays a pivotal role in shaping the dynamical evolution of giant molecular clouds (GMCs). To study the effects of stellar feedback on the star formation efficiency of the clouds and the dynamical response of embedded

Beyond coalition and opposition? The effect of councilwide agreements on legislative voting behaviour in Dutch municipalities

Swiss Political Science Review, Volume 31, Issue 2, Page 307-330, June 2025.
Abstract A well‐established finding in the field of legislative behaviour is that parliamentary voting behaviour is nearly always strongly structured by the coalition‐opposition dynamic, even beyond the issues agreed on in the coalition agreement. Can parties break the mould of this coalition‐opposition division?

Exploiting News Analytics for Volatility Forecasting

Journal of Applied Econometrics, Volume 40, Issue 1, Page 18-36, January/February 2025.
ABSTRACT This study investigates the potential of news sentiment in predicting stock market volatility. We augment traditional time series models of realized volatility with the sentiment of macroeconomic and firm‐specific news. Our results demonstrate that incorporating the sentiment of domestic macroeconomic news significantly improves volatility ...
