Planetary Nebulae and Stellar Kinematics in the Flattened Elliptical Galaxy NGC 1344 [PDF]

, 2005
We present photometric and kinematic information obtained by measuring 197 planetary nebulae (PNs) discovered in the flattened Fornax elliptical galaxy NGC 1344 (also known as NGC 1340) with an on-band, off-band, and grism+on-band filter technique.

A Systematic Review of Alternative Host Species of Phytophthora erythroseptica, the Major Causal Agent of Pink Rot of Potato

Plant Pathology, Volume 74, Issue 3, Page 605-640, April 2025.
The literature cites many alternative hosts of Phytophthora erythroseptica. However, evidence of host status is often insufficient, thus a polyphasic approach (morphological, molecular, histological and pathogenicity) is required. ABSTRACT Most published studies of Phytophthora erythroseptica, the major causal agent of pink rot of potato, have focused ...

The Globular Cluster System of the Virgo Dwarf Elliptical Galaxy VCC 1087 [PDF]

, 2005
We present an analysis of the globular cluster (GC) system of the nucleated dwarf elliptical galaxy VCC 1087 in the Virgo Cluster based on Keck LRIS spectroscopy and archival Hubble Space Telescope Advanced Camera for Surveys imaging.

Elliptical galaxies with separable potentials [PDF]

Monthly Notices of the Royal Astronomical Society, 1985
The perfect ellipsoid is presented: an inhomogeneous triaxial mass model with a gravitational potential that is of Stäckel form. The equations of motion are separable in ellipsoidal coordinates and all stellar orbits have three isolating integrals that are known explicitly.

Commodity risk assessment of Populus alba, Populus nigra and Populus tremula plants from the UK

EFSA Journal, Volume 23, Issue 3, March 2025.
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by plants of Populus alba, Populus nigra and ...

NGC 770: A Counterrotating Core in a Low-Luminosity Elliptical Galaxy [PDF]

, 2005
We present evidence for a counterrotating core in the low-luminosity (MB = -18.2) elliptical galaxy NGC 770 based on internal stellar kinematic data. This counterrotating core is unusual, as NGC 770 is not the primary galaxy in the region and lies in an ...

Causal Discovery in Astrophysics: Unraveling Supermassive Black Hole and Galaxy Coevolution

The Astrophysical Journal
Correlation does not imply causation, but patterns of statistical association between variables can be exploited to infer a causal structure (even with purely observational data) with the burgeoning field of causal discovery.

Automatic Detection of Galaxy Type From Datasets of Galaxies Image Based on Image Retrieval Approach

Scientific Reports, 2017
This paper presents a new approach for the automatic detection of galaxy morphology from datasets based on an image-retrieval approach. Currently, there are several classification methods proposed to detect galaxy types within an image.

Is AGN feedback necessary to form red elliptical galaxies?

, 2008
We have used GADGET2 to simulate the formation of an elliptical galaxy in a cosmological dark matter halo with mass 3x10^12M_Sun/h. Using a stellar population synthesis model has allowed us to compute magnitudes, colours and surface brightness profiles ...

Imaging of the protoelliptical NGC 1700 and its globular cluster system

, 2000
An excellent candidate for a young elliptical, or `protoelliptical' galaxy is NGC 1700. Here we present new B, V and I band imaging using the Keck telescope and reanalyse existing V and I band images from the Hubble Space Telescope.
