ZTF Early Observations of Type Ia Supernovae I: Properties of the 2018 Sample
Yuhan Yao, Adam A. Miller, S. R. Kulkarni +32
Early-time observations of Type Ia supernovae (SNe Ia) are essential to constrain their progenitor properties. In this paper, we present high-quality light curves of 127 SNe Ia dis…
New radio constraints on the obscured star formation rates of massive GRB hosts at redshifts 2-3.5
Pradip Gatkine, Stuart Vogel, Sylvain Veilleux
It is not clear whether gamma-ray bursts (GRBs) are unbiased tracers of cosmic star formation at . Since dusty starburst galaxies are significant contributors to the cosmic…
GROWTH on S190814bv: Deep Synoptic Limits on the Optical/Near-Infrared Counterpart to a Neutron Star-Black Hole Merger
Igor Andreoni, Daniel A. Goldstein, Mansi M. Kasliwal +49
On 2019 August 14, the Advanced LIGO and Virgo interferometers detected the high-significance gravitational wave (GW) signal S190814bv. The GW data indicated that the event resulte…
Enabling the next generation of scientific discoveries by embracing photonic technologies
Nemanja Jovanovic, Charles Beichman, Cullen Blake +46
The fields of Astronomy and Astrophysics are technology limited, where the advent and application of new technologies to astronomy usher in a flood of discoveries altering our unde…
GROWTH on S190510g: DECam Observation Planning and Follow-Up of a Distant Binary Neutron Star Merger Candidate
Igor Andreoni, Daniel A. Goldstein, Shreya Anand +23
The first two months of the third Advanced LIGO and Virgo observing run (2019 April-May) showed that distant gravitational wave (GW) events can now be readily detected. Three candi…
Astro2020: Astrophotonics White Paper
Pradip Gatkine, Sylvain Veilleux, John Mather +19
Astrophotonics is the application of versatile photonic technologies to channel, manipulate, and disperse guided light from one or more telescopes to achieve scientific objectives…
The CGM-GRB Study. I. Uncovering The CircumGalactic Medium around GRB hosts at redshifts 2-6
Pradip Gatkine, Sylvain Veilleux, Antonino Cucchiara
Recent studies have revealed a dynamic interplay between the galaxy ecosystem and the circumgalactic medium (CGM). We investigate the CGM at high redshifts (z 2) by using…
GROWTH on S190425z: Searching thousands of square degrees to identify an optical or infrared counterpart to a binary neutron star merger with the Zwicky Transient Facility and Palomar Gattini IR
Michael W. Coughlin, Tomás Ahumada, Shreya Anand +76
The third observing run by LVC has brought the discovery of many compact binary coalescences. Following the detection of the first binary neutron star merger in this run (LIGO/Virg…
A Do-it-yourself Spectrograph Kit for Educational Outreach in Optics and Photonics
Pradip Gatkine, Gregorio Zimerman, Elizabeth Warner
We designed and built a do-it-yourself spectrograph assembly to demonstrate the concept of spectroscopy, an indispensable tool for exploring the cosmos. This spectrograph is design…
Towards a multi-input astrophotonic AWG spectrograph
Pradip Gatkine, Sylvain Veilleux, Yiwen Hu +2
Astrophotonics is the new frontier technology to develop diffraction-limited, miniaturized, and cost-effective instruments for the next generation of large telescopes. For various…
Astrophotonic Spectrographs
Pradip Gatkine, Sylvain Veilleux, Mario Dagenais
Astrophotonics is the application of photonic technologies to channel, manipulate, and disperse light from one or more telescopes to achieve scientific objectives in astronomy in a…
GROWTH on S190426c. II. Real-Time Search for a Counterpart to the Probable Neutron Star-Black Hole Merger using an Automated Difference Imaging Pipeline for DECam
Daniel A. Goldstein, Igor Andreoni, Peter E. Nugent +17
The discovery of a transient kilonova following the gravitational-wave event GW170817 highlighted the critical need for coordinated rapid and wide-field observations, inference, an…
Discovery of Highly Blueshifted Broad Balmer and Metastable Helium Absorption Lines in a Tidal Disruption Event
T. Hung, S. B. Cenko, Nathaniel Roth +25
We report the discovery of non-stellar hydrogen Balmer and metastable helium absorption lines accompanying a transient, high-velocity (0.05) broad absorption line (BAL) system i…
