The far-infrared/submillimeter properties of galaxies located behind the Bullet cluster* [PDF]

, 2010
The Herschel Lensing Survey (HLS) takes advantage of gravitational lensing by massive galaxy clusters to sample a population of high-redshift galaxies which are too faint to be detected above the confusion limit of current far-infrared/submillimeter ...

How Massive Star Clusters Form and Evolve: A Near-IR Survey of the W51 Complex

The Astronomical Journal
We present near-infrared JHK _s and narrowband H _2 (1–0) photometric observations of the W51A region, obtained with GTC EMIR, aiming to characterize its young stellar population, and provide mass estimates for individual cluster members and the ...

Tunable Terahertz Generation in Dispersion‐Engineered ZnTe Waveguides

Laser &Photonics Reviews, EarlyView.
A dispersion‐engineered Zinc Telluride (ZnTe) slab waveguide platform enables tunable and efficient guided‐wave terahertz (THz) generation through modal phase matching. By tailoring the optical and THz modal dispersion, coherent THz emission is achieved across 0.1–3 THz.

Visible Octave Frequency Combs in Silicon Nitride Nanophotonic Waveguides Driven by Ti:Sapphire Lasers

Laser &Photonics Reviews, EarlyView.
Chip‐based frequency combs are usually pumped from telecom wavelengths, far from the visible. This work instead pumps close to the visible with a Ti:sapphire laser ‐ the source behind the original optical frequency combs and now becoming chip‐integrable‐ and lets silicon‐nitride waveguides convert it into efficient, octave‐spanning visible‐to‐infrared ...

Evidence for Random Walk Transport of Small Asteroids from the Main Belt to the Inner Solar System

The Planetary Science Journal
The transport of some main-belt asteroids to the inner solar system depends on Yarkovsky radiation forces changing the orbits of those asteroids. However, these forces depend on the rotational states of the asteroids, and YORP radiation forces act to ...

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

AKARI infrared bright source catalogues [PDF]

, 2010
Bright source catalogues based on the new mid- and far-infrared all-sky survey by the infrared astronomical satellite AKARI were released into the public domain in March 2010. The mid-infrared catalogue contains more than 870 thousand sources observed at
