ALMA Reveals the Molecular Gas Properties of Five Star-forming Galaxies across the Main Sequence at 3
Schinnerer, Eva; Tasca, Lidia; Liu, Daizhong +17 more
We present the detection of CO (5-4) with signal-to-noise ratio (S/N) > 7-13 and a lower CO transition with S/N > 3 (CO (4-3) for four galaxies, and CO (3-2) for one) with the Atacama Large Millimeter/submillimeter Array in bands 3 and 4 in five main-sequence (MS) star-forming galaxies with stellar masses (3-6) × 1010M⊙…
Orbital Modulation of Gamma Rays from PSR J2339-0533
An, Hongjun; Kerr, Matthew; Fermi-LAT Collaboration +1 more
We report on orbital modulation of the 100-600 MeV gamma-ray emission of the PB = 4.6 hr millisecond pulsar binary PSR J2339-0533 using 11 yr of Fermi Large Area Telescope data. The modulation has high significance (chance probability p ≈ 10-7), is approximately sinusoidal, peaks near pulsar superior conjunction, and is detec…
Chemical abundances of open clusters from high-resolution infrared spectra - II. NGC 752
Sneden, C.; Pilachowski, C. A.; Mace, G. N. +9 more
We present a detailed near-infrared chemical abundance analysis of 10 red giant members of the Galactic open cluster NGC 752. High-resolution (R ≃ 45000) near-infrared spectral data were gathered with the Immersion Grating Infrared Spectrograph, providing simultaneous coverage of the complete H and K bands. We derived the abundances of H-burning (…
The PDR structure and kinematics around the compact H II regions S235 A and S235 C with [C II], [13C II], [O I], and HCO+ line profiles
Schneider, N.; Samal, M. R.; Okada, Y. +11 more
The aim of this work is to study structure and gas kinematics in the photodissociation regions (PDRs) around the compact H II regions S235 A and S235 C. We observe the [C II], [13C II], and [O I] line emission, using SOFIA/upGREAT, and complement them by data of HCO+ and CO. We use the [13C II] line to measure the …
Hot WHIM counterparts of FUV O VI absorbers: Evidence in the line-of-sight towards quasar 3C 273
Kaastra, Jelle; Finoguenov, Alexis; Schaye, Joop +7 more
Aims: We explore the high spectral resolution X-ray data towards the quasar 3C 273 to search for signals of hot (∼106-7 K) X-ray-absorbing gas co-located with two established intergalactic far-ultraviolet (FUV) O VI absorbers.
Methods: We analyze the soft X-ray band grating data of all XMM-Newton and Chandra instruments to sea…
Flare Energy Release at the Magnetic Field Polarity Inversion Line during the M1.2 Solar Flare of 2015 March 15. II. Investigation of Photospheric Electric Current and Magnetic Field Variations Using HMI 135 s Vector Magnetograms
Zimovets, I. V.; Sharykin, I. N.; Myshyakov, I. I.
This work is a continuation of Paper I and is devoted to the analysis of nonthermal electron dynamics and plasma heating in the confined M1.2 class solar flare SOL2015-03-15T22:43, revealing energy release in the highly sheared interacting magnetic loops in the low corona, above the polarity inversion line (PIL). The aim of the present work is to …
The nuclear architecture of NGC 4151: on the path toward a universal outflow mechanism in light of NGC 1068
Williams, D. R. A.; Steiner, J. E.; May, D. +2 more
We report near-infrared integral field spectroscopic observations of the active galactic nucleus NGC 4151 with archive data from the NIFS-Gemini North Telescope. We have selected best-seeing observations (≲0.3 arcsec) that, allied to our methodology of image processing techniques, show structures with spatial resolution comparable to those of the …
Characterization of the Particle-induced Background of XMM-Newton EPIC-pn: Short- and Long-term Variability
Miller, Eric D.; Kraft, Ralph; Gastaldello, Fabio +16 more
The particle-induced background of X-ray observatories is produced by galactic cosmic ray (GCR) primary protons, electrons, and He ions. Events due to direct interaction with the detector are usually removed by onboard processing. The interactions of these primary particles with the detector environment produce secondary particles that mimic X-ray…
The catalogue of cometary orbits and their dynamical evolution
Dybczyński, Piotr A.; Królikowska, Małgorzata
We present the CODE catalogue, the new cometary catalogue containing data for almost 300 long-period comets that were discovered before 2018. This is the first catalogue containing cometary orbits in the five stages of their dynamical evolution and covering three successive passages through the perihelion, with the exception of the hyperbolic come…
Bright Lyman-α emitters among Spitzer SMUVS galaxies in the MUSE/COSMOS field
Caminha, G. B.; Caputi, K. I.; Rosani, G. +1 more
We search for the presence of bright Lyα emitters among Spitzer SMUVS galaxies at z > 2.9 making use of homogeneous MUSE spectroscopic data. Although these data only cover a small region of COSMOS, MUSE has the unique advantage of providing spectral information over the entire field, without the need of target pre-selection. This results in an …
