The Hubble Space Telescope PanCET Program: An Optical to Infrared Transmission Spectrum of HAT-P-32Ab
Nikolov, Nikolay; Mikal-Evans, Thomas; Sing, David K. +14 more
We present a 0.3-5 µm transmission spectrum of the hot Jupiter HAT-P-32Ab observed with the Space Telescope Imaging Spectrograph and Wide Field Camera 3 instruments mounted on the Hubble Space Telescope, combined with Spitzer Infrared Array Camera photometry. The spectrum is composed of 51 spectrophotometric bins with widths ranging between …
Integral Field Spectroscopy of Fast Outflows in Dwarf Galaxies with AGNs
Veilleux, Sylvain; Liu, Weizhe; Bohn, Thomas +4 more
Feedback likely plays a vital role in the formation of dwarf galaxies. While stellar processes have long been considered the main source of feedback, recent studies have revealed tantalizing signs of active galactic nucleus (AGN) feedback in dwarf galaxies. In this paper, we report the results from an integral field spectroscopic study of a sample…
Impact of polarised extragalactic sources on the measurement of CMB B-mode anisotropies
Lagache, G.; Montier, L.; Tucci, M. +2 more
One of the main goals of cosmology is to search for the imprint of primordial gravitational waves in the polarisation filed of the cosmic microwave background to probe inflation theories. One of the obstacles in detecting the primordial signal is that the cosmic microwave background B-mode polarisation must be extracted from among astrophysical co…
Distances and Statistics of Local Molecular Clouds in the First Galactic Quadrant
Su, Yang; Yan, Qing-Zeng; Sun, Yan +2 more
We present an analysis of local molecular clouds ( $-6\lt {V}_{\mathrm{LSR}}\lt 30$ km s-1, i.e., <1.5 kpc) in the first Galactic quadrant ( $25\buildrel{\circ}\over{.} 8\lt l\lt 49\buildrel{\circ}\over{.} 7$ and $| b| \lt 5^\circ $ ), a pilot region of the Milky Way Imaging Scroll Painting (MWISP) CO survey. Using the Spectral Clust…
Search for Optically Dark Infrared Galaxies without Counterparts of Subaru Hyper Suprime-Cam in the AKARI North Ecliptic Pole Wide Survey Field
Momose, Rieko; Hashimoto, Tetsuya; Goto, Tomotsugu +25 more
We present the physical properties of AKARI sources without optical counterparts in optical images from the Hyper Suprime-Cam (HSC) on the Subaru telescope. Using the AKARI infrared (IR) source catalog and HSC optical catalog, we select 583 objects that do not have HSC counterparts in the AKARI North Ecliptic Pole wide survey field (∼5 deg2
Swift-XRT follow-up of gravitational wave triggers during the third aLIGO/Virgo observing run
Troja, E.; Cenko, S. B.; Sakamoto, T. +41 more
The Neil Gehrels Swift Observatory followed up 18 gravitational wave (GW) triggers from the LIGO/Virgo collaboration during the O3 observing run in 2019/2020, performing approximately 6500 pointings in total. Of these events, four were finally classified (if real) as binary black hole (BH) triggers, six as binary neutron star (NS) events, two each…
ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP). II. Survey Overview: A First Look at 1.3 mm Continuum Maps and Molecular Outflows
Sanhueza, Patricio; Ward-Thompson, Derek; Kwon, Woojin +32 more
Planck Galactic Cold Clumps (PGCCs) are considered to be the ideal targets to probe the early phases of star formation. We have conducted a survey of 72 young dense cores inside PGCCs in the Orion complex with the Atacama Large Millimeter/submillimeter Array (ALMA) at 1.3 mm (band 6) using three different configurations (resolutions ∼0"35, 1"0, an…
The CARMENES search for exoplanets around M dwarfs. LP 714-47 b (TOI 442.01): populating the Neptune desert
Barbieri, M.; Amado, P. J.; Bauer, F. F. +118 more
We report the discovery of a Neptune-like planet (LP 714-47 b, P = 4.05204 d, mb = 30.8 ± 1.5M⊕, Rb = 4.7 ± 0.3 R⊕) located in the "hot Neptune desert". Confirmation of the TESS Object of Interest (TOI 442.01) was achieved with radial-velocity follow-up using CARMENES, ESPRESSO, HIRES, iSHELL, and PFS, a…
Magnetic Reconnection Inside a Flux Rope Induced by Kelvin-Helmholtz Vortices
Liu, Y.; Russell, C. T.; Escoubet, C. P. +23 more
On 5 May 2017, MMS observed a crater-type flux rope on the dawnside tailward magnetopause with fluctuations. The boundary-normal analysis shows that the fluctuations can be attributed to nonlinear Kelvin-Helmholtz (KH) waves. Reconnection signatures such as flow reversals and Joule dissipation were identified at the leading and trailing edges of t…
The Surprisingly Low Carbon Mass in the Debris Disk around HD 32297
Henning, Thomas; Hughes, A. Meredith; Redfield, Seth +18 more
Gas has been detected in a number of debris disks. It is likely secondary, I.e., produced by colliding solids. Here, we report ALMA Band 8 observations of neutral carbon in the CO-rich debris disk around the 15-30 Myr old A-type star HD 32297. We find that C0 is located in a ring at ∼110 au with an FWHM of ∼80 au and has a mass of (3.5 …
