Watching the solar eclipse Monday? Our expert has advice on how to do it safely

It's being called a "once in a lifetime" opportunity and Monday's solar eclipse has almost everybody on the continent talking as well as planning and preparing to get a glimpse of this rare astronomical moment. Amid the excitement is a need for people to view the event safely, which is why NBC Connecticut recently caught up with UConn Associate Professor of Physics Jonathan Trump to explain what's happening and, if you're going to be gazing upwards, what you need to know and how to do it without getting hurt. An astronomical celebration is just around the corner. But if you want to see the solar eclipse for yourself, there are steps you need to take to do so safely. First and foremost: to watch this out-of-this-world display April 8, don’t even think about looking right at the sun. “Most important thing, do not look directly at the solar eclipse with your eyes,” said UConn associate professor of physics Jonathan Trump. “Here in Connecticut the eclipse will be about 90% which is pretty spectacular, but even 10% of the sun’s light is a lot of the sun’s light.” UConn is one of many organizations around the state holding a celebration and viewing event. “The next one is not going to be for another 20 years, so yeah this is a special event,” said Trump. Sunglasses aren’t strong enough to protect your retinas from these UV rays. “The ultraviolet light is what give us sunburns and it can severely damage the retina in the back of your eye and permanently scar your vision. So do not look directly at the sun,” said Trump. You can view the solar eclipse safely with certified solar eclipse glasses. If you wear eyeglasses, put the solar eclipse glasses on top of your glasses. And if you have solar eclipse glasses from the last phenomena visible stateside, which was seven years ago, you should get a new pair. Experts we spoke to say they have no more than a three-year shelf life.  Looking to know more?  Jonathan Trump is an observational astronomer and is available to speak with reporters about Monday's eclipse.

Biography

Jonathan Trump is an observational astronomer who studies active galaxies, which are galaxies with accreting supermassive black holes. He is particularly interested in the co-evolving growth of black holes and galaxies: How do galaxies feed their black holes, and how do black holes influence star formation in their host galaxies.

Because active galaxies emit over a wide range of energies, he utilizes telescopes spanning the electromagnetic spectrum. He has experience observing x-rays (Chandra, XMM-Newton), ultraviolet (GALEX), optical (Hubble, Keck, Subaru, Magellan), infrared (Spitzer, Herschel), and radio (VLA) light. He has been awarded several programs on the James Webb Space Telescope to understand the formation and growth of the first black holes and galaxies.

There's a slight chance Connecticut will have a view of the northern lights tonight

Hearst Connecticut Media  print

2023-11-13

The aurora borealis was visible last night, glowing in the Massachusetts, New Hampshire and Maine skies, with reports coming in from the Mount Washington Observatory. But might it be possible to see those northern lights tonight in Connecticut?

Jonathan Trump, professor of astronomy at the University of Connecticut, told CT Insider that there might still be a chance tonight, but it’s hard to say for sure.

CEERS MIRI Imaging: Data Reduction and Quality Assessment

The Astrophysical Journal Letters

2023

The Cosmic Evolution Early Release Science Survey (CEERS), targeting the Extended Groth Strip extragalactic field, is one of the James Webb Space Telescope Director's Discretionary Early Release Science programs. To date, all observations have been executed and include NIRCam/MIRI imaging and NIRSpec/NIRCam spectroscopic exposures. Here we discuss the MIRI imaging, which includes eight pointings, four of which provide deep imaging with the bluer bands (F560W and F770W) and four of which provide contiguous wavelength coverage in F1000W, F1280W, F1500W, and F1800W, where two of these also include coverage in F770W and F2100W.

The Sloan Digital Sky Survey Reverberation Mapping Project: The Black Hole Mass–Stellar Mass Relations at 0.2≲ z≲ 0.8

The Astrophysical Journal

2023

We measure the correlation between black hole mass M BH and host stellar mass M* for a sample of 38 broad-line quasars at 0.2≲ z≲ 0.8 (median redshift z med= 0.5). The black hole masses are derived from a dedicated reverberation mapping program for distant quasars, and the stellar masses are derived from two-band optical+ IR Hubble Space Telescope imaging. Most of these quasars are well centered within≲ 1 kpc from the host galaxy centroid, with only a few cases in merging/disturbed systems showing larger spatial offsets. Our sample spans two orders of magnitude in stellar mass (∼ 10 9–10 11 M⊙) and black hole mass (∼ 10 7–10 9 M⊙) and reveals a significant correlation between the two quantities.

A CEERS Discovery of an Accreting Supermassive Black Hole 570 Myr after the Big Bang: Identifying a Progenitor of Massive z> 6 Quasars

The Astrophysical Journal Letters

2023

We report the discovery of an accreting supermassive black hole at z= 8.679. This galaxy, denoted here as CEERS_1019, was previously discovered as a Lyα-break galaxy by Hubble with a Lyα redshift from Keck. As part of the Cosmic Evolution Early Release Science (CEERS) survey, we have observed this source with JWST/NIRSpec, MIRI, NIRCam, and NIRCam/WFSS and uncovered a plethora of emission lines. The Hβ line is best fit by a narrow plus a broad component, where the latter is measured at 2.5σ with an FWHM∼ 1200 km s− 1. We conclude this originates in the broadline region of an active galactic nucleus (AGN).
