High-Resolution Near-Infrared Imaging of the Powerful Radio Galaxy 3C 324 at z = 1.21 with the Subaru Telescope

, 2000
We have obtained high-resolution K'-band images of the powerful z=1.206 radio galaxy 3C 324 with the Subaru telescope under seeing conditions of 0.3--0.4 arcsec.

Relevance of Murchison Widefield Array Interplanetary Scintillation Observations to Heliospheric Transient Catalogs

Space Weather, Volume 23, Issue 12, December 2025.
Abstract We have conducted a comprehensive comparison of interplanetary scintillation (IPS) observations taken by the Murchison Widefield Array (MWA) with several heliospheric transient event catalogs, over a time period of 7 months during solar minimum.

Searching for tidal tails - investigating galaxy harassment

, 2005
Galaxy harassment has been proposed as a physical process that morphologically transforms low surface density disc galaxies into dwarf elliptical galaxies in clusters.

A new genus of jumping spiders (Araneae: Salticidae) inhabiting the South Island New Zealand rocky alpine zone

New Zealand Journal of Zoology, Volume 52, Issue 5, Page 716-795, December 2025.
ABSTRACT The spider family Salticidae (jumping spiders) is among the most heavily researched groups of invertebrates globally. Nevertheless, in Aotearoa New Zealand most species have never been studied. While it is estimated that approximately 200 endemic salticid species are found across the country, only around 50 have been described and fewer than ...

The Planetary Nebula System and Dynamics in the Outer Halo of NGC 5128

, 2003
The halos of elliptical galaxies are faint and difficult to explore, but they contain vital clues to both structure and formation. We present the results of an imaging and spectroscopic survey for planetary nebulae (PNe) in the nearby elliptical NGC 5128.

From cells to pixels: A decision tree for designing bioimage analysis pipelines

Journal of Microscopy, Volume 300, Issue 3, Page 384-408, December 2025.
Abstract Bioimaging has transformed our understanding of biological processes, yet extracting meaningful information from complex datasets remains a challenge, particularly for biologists without computational expertise. This paper proposes a simple general approach, to help identify which image analysis methods could be relevant for a given image ...

Galaxy Formation from the Primordial Black Holes

EPJ Web of Conferences, 2017
Supermassive black hole (SMBH) of size MBH = 106-10M⊙ is common in the Universe and it defines the center of the galaxy. A galaxy and the SMBH are generally thought to have co-evolved.

Evidence for the Evolution of Young Early-Type Galaxies in the GOODS/CDF-S Field

, 2007
We have developed an efficient photometric technique for identifying young early-type galaxy candidates using a combination of photometric redshifts, spectral-type classification, and optical/near-infrared colors.

New Arabic Records From Cairo on Supernovae 1181 and 1006

Astronomische Nachrichten, Volume 346, Issue 9, November 2025.
ABSTRACT The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000–5000 year), the unusual star IRAS00500+6713 with a surrounding nebula (Pa‐30) has an expansion age not inconsistent with a SN Iax explosion in ad 1181 under the assumption that neither acceleration nor ...

Dissipational versus Dissipationless Galaxy Formation and the Dark Matter Content of Galaxies

, 2010
We examine two extreme models for the build-up of the stellar component of luminous elliptical galaxies. In one case, we assume the build-up of stars is dissipational, with centrally accreted gas radiating away its orbital and thermal energy; the dark ...
