, 2001 We present near-infrared spectra with resolutions of lambda/dlambda~1200 in the emission lines of Pa-beta, [FeII] (1.2567um), Br-gamma, and H2 v=1-0S(1) of the nuclei and circumnuclear regions of the four Seyfert 2 galaxies Mk 1066, NGC 2110, NGC 4388 ...

H{\alpha} Imaging of Nearby Seyfert Host Galaxies [PDF]
, 2016 We used narrowband interference filters with the CCD imaging camera on the Nickel 1.0 meter telescope at Lick Observatory to observe 31 nearby (z < 0.03) Seyfert galaxies in the 12 {\mu}m Active Galaxy Sample.

A search for double-peaked narrow emission line galaxies and AGNs in the LAMOST DR1 [PDF]
, 2014 The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) has released more than two million spectra, which provide the opportunity to search for double-peaked narrow emission line (NEL) galaxies and active galactic nuclei (AGNs). The double-

Ecography, EarlyView.Developing species distribution models (SDMs) requires high‐quality species occurrence records. These records, stemming from various sources with different sampling procedures, are often archived in open‐access databases, making automated data quality checks inevitable.

An Hα Impression of Lyα Galaxies at z ≃ 6 with Deep JWST/NIRCam Imaging
The Astrophysical Journal Letters, 2023 We present a study of seven spectroscopically confirmed (Ly α -emitting) galaxies at redshift z ≃ 6 using the JWST/NIRCam imaging data. These galaxies, with a wide range of Ly α luminosities, were recently observed in a series of NIRCam broad and medium ...

S0 Galaxies: Outer Gas Accretion through Tidal Interaction and Minor Merging
Galaxies, 2023 To clarify the sources of outer gas accretion onto disk galaxies, we study the vicinity of four interacting galaxy systems in the Hα emission line by using the scanning Fabry–Perot interferometer of the 6m telescope of the Special Astrophysical ...

The Balmer decrement of SDSS galaxies [PDF]
, 2011 High resolution spectra are necessary to distinguish and correctly measure the Balmer emission lines due to the presence of strong metal and Balmer absorption features in the stellar continuum.

ESC Heart Failure, EarlyView.This state‐of‐the‐art review outlines a practical, evidence‐based framework for early acute heart failure management to address critical gaps in current guidance and improve early treatment outcomes. Key components include early identification of co‐existing conditions, bedside haemodynamic profiling, a structured diagnostic approach incorporating both

Chemical Abundances of a Sample of Oxygen-dominated Galaxies
The Astrophysical Journal, 2023 We spectroscopically analyzed a sample of 85 Sloan Digital Sky Survey compact, oxygen-dominated galaxies located at redshift z ∼ 0.001–0.350, selected because of their large equivalent width of [O iii ] λ 5007 (larger than 200 Å). These galaxies might be
