MINDS: The JWST MIRI Mid-INfrared Disk Survey
Henning, Thomas; Waters, L. B. F. M.; Östlin, Göran +43 more
The study of protoplanetary disks has become increasingly important with the Kepler satellite finding that exoplanets are ubiquitous around stars in our galaxy and the discovery of enormous diversity in planetary system architectures and planet properties. High-resolution near-IR and ALMA images show strong evidence for ongoing planet formation in…
AstroSat/UVIT Study of the Diffuse Ultraviolet Radiation in the Dwarf Galaxy Holmberg II
Shalima, P.; Gogoi, Rupjyoti; Bordoloi, Olag Pratim +4 more
We present measurements of diffuse ultraviolet (UV) emission in the dwarf irregular galaxy Holmberg II obtained with the Ultra Violet Imaging Telescope (UVIT) instrument onboard AstroSat, India's first multiwavelength space mission. With a spatial resolution of 1.″2–1.″6, these are the highest resolution UV observations of the galaxy to date. We f…
Low Mass Stars as Tracers of Star and Cluster Formation
Megeath, S. T.; Gutermuth, R. A.; Kounkel, M. A.
We review the use of young low mass stars and protostars, or young stellar objects (YSOs), as tracers of star formation. Observations of molecular clouds at visible, infrared, radio and X-ray wavelengths can identify and characterize the YSOs populating these clouds, with the ability to detect deeply embedded objects at all evolutionary stages. Su…
Herschel Observations of Disks around Late-type Stars
Gizis, John E.; Plavchan, Peter; Matrá, Luca +9 more
A set of twenty late-type (K5-M5) stars were observed with the Herschel Space Observatory at 100 and 160 microns with the goal of searching for far-infrared excesses indicative of the presence of circumstellar disks. Out of this sample, four stars (TYC 7443-1102-1, TYC 9340-437-1, GJ 784 and GJ 707) have infrared excesses above their stellar photo…
The Faint Optical Counterparts Catalog at 19.4 < r < 22 mag from Herschel-ATLAS SDP Field
Wu, Hong; Zhu, Yi-Nan; Zhou, Zhi-Min +2 more
We carry out a spectroscopic survey with Hectospec mounted on the 6.5 m Multiple Mirror Telescope to obtain redshifts of optical counterparts of the Herschel-ATLAS sources in the science demonstration phase field. Our work concerns counterparts with a magnitude range at $19.4\lt {r}_{\mathrm{SDSS}}\lt 22$ mag. The observation covers two $\sim 1\ {…
DustPedia: A Definitive Study of Cosmic Dust in the Local Universe
Bianchi, S.; Smith, M.; Fritz, J. +20 more
The European Space Agency has invested heavily in two cornerstones missions: Herschel and Planck. The legacy data from these missions provides an unprecedented opportunity to study cosmic dust in galaxies so that we can, for example, answer fundamental questions about the origin of the chemical elements, physical processes in the interstellar medi…
The SCUBA-2 850 µm Follow-up of WISE-selected, Luminous Dust-obscured Quasars
Knudsen, Kirsten K.; Fan, Lulu; Han, Yunkun +1 more
Hot dust-obscured galaxies (Hot DOGs) are a new population recently discovered in the Wide-field Infrared Survey Explorer All-Sky survey. Multiwavelength follow-up observations suggest that they are luminous, dust-obscured quasars at high redshift. Here we present the JCMT SCUBA-2 850 µm follow-up observations of 10 Hot DOGs. Four out of ten…
Spectro-Imaging of the Asymmetric Inner Molecular and Dust Shell Region of the Mira Variable W Hya with MIDI/VLTI
Quirrenbach, A.; Lopez, B.; Kerschbaum, F. +4 more
Not Available
Based on observations made with the Very Large Telescope Interferometer (VLTI) at the Paranal Observatory under program IDs 083.D-0294, 084.D-0334, and 085.D-0201.Scanamorphos: A Map-making Software for Herschel and Similar Scanning Bolometer Arrays
Roussel, H.
Scanamorphos is one of the public softwares available to post-process scan observations performed with the Herschel photometer arrays. This post-processing mainly consists in subtracting the total low-frequency noise (both its thermal and non-thermal components), masking high-frequency artefacts such as cosmic ray hits, and projecting the data ont…
An Overview of the Dwarf Galaxy Survey
Poglitsch, A.; Sturm, E.; Ciesla, L. +38 more
The Dwarf Galaxy Survey (DGS) program is studying low-metallicity galaxies using 230 hr of far-infrared (FIR) and submillimetre (submm) photometric and spectroscopic observations of the Herschel Space Observatory and draws from this a rich database of a wide range of wavelengths tracing the dust, gas and stars. This sample of 50 galaxies includes …
