0.9-18um obs. of SN 2021afdx
We present near- and mid-infrared (0.9-18{mu}m) photometry of supernova (SN) 2021afdx, which was imaged serendipitously with the James Webb Space Telescope (JWST) as part of its... -
Brackett emission lines in young star APOGEE sp.
Very young (t<~10Myr) stars possess strong magnetic fields that channel ionized gas from the interiors of their circumstellar disks to the surface of the star. Upon impacting... -
Radial velocities measurements of Castor Aa and Ba
Castor is a system of six stars in which the two brighter objects, Castor A and B, revolve around each other every ~450yr and are both short-period spectroscopic binaries. They... -
X-ray to FIR observations for an AGN sample
The high-ionization mid-IR lines, excited in the narrow-line regions of active galactic nuclei (AGN), barely affected by stellar excitation and dust extinction, trace the AGN... -
X-SHOOTER/ALMA QSOs at 5.7<~z<~7.6. II. BH masses
We present measurements of black hole masses and Eddington ratios ({lambda}Edd) for a sample of 38 bright (M_1450_<-24.4mag) quasars at 5.8<~z<~7.5, derived from Very... -
Early results from GLASS-JWST. VI. NIRISS WFFS
Wide Field Slitless Spectroscopy (WFSS) provides a powerful tool for detecting strong line emission in star-forming galaxies (SFGs) without the need for target preselection. As... -
GTC 8-13um spectropolarimetry toward CygOB2-12
We present the first mid-IR detection of the linear polarization toward the star CygOB2-12, a luminous blue hypergiant that, with A_V_~10mag of foreground extinction, is a... -
An updated distance-calibrated SED of Gl 229B
We present results from an atmospheric retrieval analysis of Gl 229B using the Brewster retrieval code. We find the best fit model to be cloud-free, consistent with the T dwarf... -
HeI{lambda}10830 in red giant stars with HET/HPF
We have gathered near-infrared zyJ-band high-resolution spectra of nearly 300 field red giant stars with known lithium abundances in order to survey their HeI{lambda}10830... -
CHAOS. VII. Large-scale abundance study in M33
The dispersion in chemical abundances provides a very strong constraint on the processes that drive the chemical enrichment of galaxies. Due to its proximity, the spiral galaxy... -
Mid-IR PAH features of SINGS galaxies
We combined mapping-mode mid-infrared Spitzer spectra with complementary infrared imaging to perform a spatially resolved study of polycyclic aromatic hydrocarbon (PAH) emission... -
New identifications of 4FGL sources with SPT-SZ
The fourth Fermi Large Area Telescope catalog (4FGL) contains 5064 {gamma}-ray sources detected at high significance, but 26% of them still lack associations at other... -
PHATTER. IV. Star cluster catalog
We construct a catalog of star clusters from Hubble Space Telescope images of the inner disk of the Triangulum Galaxy (M33) using image classifications collected by the Local... -
VLT-KMOS NIR sp. of SSTc2d J163134.1-240060
We report the serendipitous discovery of an elliptical shell of CO associated with the faint stellar object SSTc2d J163134.1-240060 as part of the "Ophiuchus Disk Survey... -
JWST morphological measurements at 4.4um & 1.5um
Galaxy sizes and their evolution over cosmic time have been studied for decades and serve as key tests of galaxy formation models. However, at z>~1 these studies have been... -
Chandra obs. of the Trifid region & ARCoIRIS sp.
The dynamical states of molecular clouds may affect the properties of the stars they form. In the vicinity of the Trifid Nebula (d=1180+/-25pc), the main star cluster (Trifid... -
Variability of Sgr A* in 2019 July
We report a timing analysis of near-infrared (NIR), X-ray, and submillimeter data during a 3 day coordinated campaign observing Sagittarius A. Data were collected at 4.5um with... -
Massive YSOs in the GC. II. IRTF spectra
To study the demographics of interstellar ices in the Central Molecular Zone (CMZ) of the Milky Way, we obtain near-infrared spectra of 109 red point sources using NASA... -
Infrared LC and spectrum of Scutum X-1 system
The symbiotic X-ray binary Sct X-1 was suggested to be the first known neutron star accreting from a red supergiant companion. Although known for nearly 50yr, detailed... -
Phot. and sp. obs. of type Ia SN 2015bo
We present optical and near-infrared photometric and spectroscopic observations of the fast-declining Type Ia supernova (SN) 2015bo. SN2015bo is underluminous...
