Black Hole Properties of Type 1 Active Galactic Nuclei in the North Ecliptic Pole Wide Field. I. Mid-infrared Sources with Optical Counterparts

Dohyeong Kim, Myungshin Im, Hyunjin Shim, Minjin Kim et autres

Abstract We present measurements of black hole (BH) properties of 861 type 1 active galactic nuclei (AGNs) in the North Ecliptic Pole (NEP)-Wide field. These AGNs are detected in both optical and mid-infrared (MIR) surveys and are identified as type 1 AGNs …

Machine Learning–based Photometric Redshifts for Galaxies in the North Ecliptic Pole Wide Field: Catalogs of Spectroscopic and Photometric Redshifts

Taewan Kim, Jubee Sohn, Ho Seong Hwang, Simon C-C Ho et autres

Abstract We perform an MMT/Hectospec redshift survey of the North Ecliptic Pole Wide (NEPW) field covering 5.4 deg2 and use it to estimate the photometric redshifts for the sources without spectroscopic redshifts. By combining 2572 newly measured redshifts from our survey with …

The Calibration of Polycyclic Aromatic Hydrocarbon Dust Emission as a Star Formation Rate Indicator in the AKARI NEP Survey

Helen Kyung Kim, Matthew A. Malkan, Toshinobu Takagi, Nagisa Oi et autres

Abstract Polycyclic aromatic hydrocarbon (PAH) dust emission has been proposed as an effective extinction-independent star formation rate (SFR) indicator in the mid-infrared, but this may depend on conditions in the interstellar medium. The coverage of the AKARI/Infrared Camera (IRC) allows us to …

A GMRT 610 MHz radio survey of the North Ecliptic Pole (NEP, ADF-N) / Euclid Deep Field North

Glenn J. White, Laia Barrufet, Stephen Serjeant, C. P. Pearson et autres

ABSTRACT This paper presents a 610 MHz radio survey covering 1.94 deg$^2$ around the North Ecliptic Pole (NEP), which includes parts of the ${\it AKARI}$ (ADF-N) and Euclid, Deep Fields North. The median 5$\sigma$ sensitivity is 28 $\mu$Jy beam$^{-1}$, reaching as low …

Chandra Survey in the AKARI deep field at the North Ecliptic Pole

T. Miyaji, Blanca Bravo-Navarro, J. Díaz Tello, M. Krumpe et autres

Aims. We present a catalog of optical and infrared (NIR) identifications (ID) of X-ray sources in the AKARI North Ecliptic Pole (NEP) deep field detected with Chandra, covering ~0.34 deg2 and with 0.5–2 keV flux limits ranging between ~2–20 × 10−16 erg …

North Ecliptic Pole merging galaxy catalogue

William Pearson, L. E. Suelves, Simon C-C Ho, Nagisa Oi et autres

Aims.We aim to generate a catalogue of merging galaxies within the 5.4 sq. deg. North Ecliptic Pole over the redshift range 0.0 <z <0.3. To do this, imaging data from the Hyper Suprime-Cam are used along with morphological parameters derived from these …
