Galaxies and Black Holes in the First Billion Years

Trying to catch up on recent developments in galaxy formation? I can heartily recommend an excellent review article on the subject by Richard Ellis which you can find on the arXiv here. The abstract reads:

 I present written notes from three lectures given at the 54th Saas-Fee Advanced Course of the Swiss Society of Astrophysics and Astronomy in January 2025 entitled “Galaxies and Black Holes in the First Billion Years as seen by the JWST”. I focused my lectures on progress in studies of cosmic reionisation, the properties of galaxies in the reionisation era, topics related to the redshift frontier and the search for Population III stars. The lectures were given to graduate students in astrophysics and cover both pedagogical material as well as observational results from the first two and half years of JWST science operations. The pace of discovery with JWST is, of course, rapid and so my lectures discuss long-term goals, analysis methods and their assumptions and limitations in the hope that the underlying material will retain value in the near future. In this written version, the visual material is that presented at Saas-Fee in January 2025 but I have provided updates on progress from the literature up to August 2025. The material is aimed at early career researchers and should not be considered as a scholarly review of the entire JWST literature on high redshift galaxies.

It’s quite a long article (65 pages) but nicely written and well worth reading, as it is full of information about recent advances as well as historical insights. Talking of which, there’s a picture on page 41 taken at a meeting in Durham in 1988 called The Epoch of Galaxy Formation that I attended while I was still a graduate student:

Richard Ellis himself is in the front row, left of centre with light-coloured trousers, checked shirt and hands in pockets. I’m in the picture too, but I’ll leave it up to you to find me!

A poll was held among the delegates at that meeting about various questions to do with galaxy formation. The majority opinions revealed by these votes nearly all turned out to be utterly wrong! That’s progress, I guess…

Pop cryptid chatter: Beards and encryptids

My favorite fringe topic has always been cryptozoology, which is the intersection of animals and mysterious weirdness. As I’ve written about the subject of “pop cryptids”, fabulous monsters are now mainstream. They have become ubiquitous online and in American culture, not so much as possibly real zoological organisms to be scientifically recognized (because none have been) but as symbols, icons, and genii locorum (spirits of a place). It’s my opinion that these current depictions of cryptids are where the fascinating content lies, and that there is little value in considering cryptozoology as a zoological endeavor. The reasoning is complex but that leaves so much left to explore for these cultural concepts. For this post, I’m sharing some pop cryptid related items I found this week.

For more on Pop Cryptids, head to Pop Goes the Cryptid or see other posts here.

Cryptozoologists, represent!

Did you ever notice something in common between featured speakers of cryptid conferences?

What is with the beards?! Yep. Every one of these are guys with beards. (Hats may be an indicator of which of them are less “academic” and more field-oriented.) You may recognize a few of these usual suspects.

It’s all too easy to apply these generalized characteristics to those interested in particular fringe topics. (Maybe it’s just me, because I’m not a beard-fan.) And, I will admit, it’s not totally fair. That is, the audience is more diverse. The photo above was from the 2023 Florida Bigfoot event in which a YouTube video of the vendor room showed, Ok, many more beards, but also many women and some kids. Regardless of the audience, the narrow demographic appearing on the stage representing the leadership in this community is glaring. The invited speakers are not scientists (except for usually one who flashes that label for cred – last year J. Meldrum and this year R. Holland). The story, not the science, is the star. To me, that says something important.

The 2024 event just took place last weekend and not much has changed. The generalization holds.

Additional photos show that the appeal of the idea of Sasquatch, and all the cute and kitschy stuff related to it, is embraced by the younger generation because it’s fun. Not so much because they really think it’s a legit undiscovered animal.

From the NPR affiliate in Florida:

[Organizer] Pippin estimated that more than 2,000 people in total visited the conference, which featured a stage for speakers and about 45 vendors.

Ryan “RPG” Golembeske, 48, served as master of ceremonies.

“You are in the one absolute safe place to go all in on the squatch,” Golembeske said to the crowd. “Everybody here wants to talk about it. Everybody here is obsessed with it.”

I don’t think it’s healthy to be obsessed with an unproven creature. But, that’s a word that’s maybe overused these days. Maybe not.

And cryptid proponents love to tout how youngsters are getting into the cryptozoology act and often give them a platform. However, I’ve seen many such teens grow out of belief in forest monsters as real life dawns on them. Some stay hooked all their lives. Since we have 50+ years of actively looking for Bigfoot and not finding it, this seems like a highly questionable obsession.

The Encryptids

This week saw the Electronic Frontier Foundation launch their membership drive featuring The Encryptids – “the rarely-seen enigmas who inspire campfire lore. But this time, they’re spilling secrets about how they survive this ever-digital world.”

It doesn’t take a genius to figure out that cryptid creatures can be creatively used for cryptocurrency and encryption. This promotional material is charming.

Note the appealing “cute” factor – a key to reaching a wide audience. It also appears EFF will be loose with the cryptid label by featuring not just Bigfoot, but a Jackalope and maybe a ghost. I do like it, though. Why not? It’s a good cause.

For your listening pleasure

Besides the Jackalope, a famous manufactured animal of renown is the Hodag, the official mascot of Rhinelander, Wisconsin. I want to recommend the Urban Legends podcast episode on the Hodag written and hosted by Luke Mordue.

Check it out here. And have a listen to the other Modern Myths episodes.

Passing of Richard Ellis

Finally, I was sorry to hear of the passing of Richard Ellis, 86, an author and artist who greatly informed me about marine life. His Monsters and the Sea is one of my top cryptozoology books.

I recommend his NYT obituary and this tribute by Darren Naish on Tet Zoo.

It is a sign of a life well-lived when you leave behind your lauded words, images, and ideas to continue on.
